RELEASE NOTES FOR LIBGUESTFS 1.40

       These release notes only cover the differences from the previous stable/dev branch split
       (1.38.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       New features in existing tools

       Virt-inspector now displays the libosinfo short ID for guests (Pino Toscano).

       Guestfish -N will now generate 1G disks instead of 100M disks by default.

       Virt-resize supports f2fs filesystems (Pino Toscano).

       libguestfs-test-tool now supports bash tab completion (Pino Toscano).

       The --machine-readable option now supports sending output to files or stdout/stderr.  This
       works uniformly across most OCaml-based virt tools, specifically: virt-builder, virt-
       builder-repository, virt-dib, virt-get-kernel, virt-resize, virt-sparsify, and virt-v2v
       (Pino Toscano).

       Virt-builder --uninstall option now works on SUSE (Sebastian Meyer).

       Virt-builder now supports Windows.  We are not able to ship Windows templates in the
       public respository for obvious licensing reasons, but if you are an MSDN subscriber you
       may build your own.  See
       https://rwmj.wordpress.com/2018/09/13/creating-windows-templates-for-virt-builder/

       Many tools now support a --key option allowing you to pass in decryption keys for
       filesystems stored in local files on the host rather than having to feed them in over
       stdin (Pino Toscano).

       virt-v2v and virt-p2v

       New -o rhv-upload mode for directly uploading images to RHV, bypassing the Export Storage
       Domain (Tomáš Golembiovský, Nir Soffer, Daniel Erez, Pino Toscano).

       New -o openstack mode for directly uploading images to OpenStack and Cinder using
       OpenStack APIs.

       Virt-v2v now has a general mechanism for input and output options: -io and -oo.

       Virt-v2v can now install the RHV tools or QEMU GA in guests (Tomáš Golembiovský).

       The huge manual has now been split into several smaller documents and is more focused on
       helping users to accomplish specific v2v tasks.

       Multiple improvements to the OVF metadata when converting to RHV (Tomáš Golembiovský, Pino
       Toscano, Arik Hadas).

       Virt-v2v can now convert Linux guests with split kernel packages, especially Ubuntu 18.04
       (Pino Toscano).

       Virt-v2v old --password-file option has been replaced by -ip (the old option remains for
       backwards compatibility).

       Virt-v2v now preserves the VM Generation ID.

       Virt-v2v has a new --mac option allowing specific NICs to be mapped precisely to networks
       or bridges on the target.

       New virt-v2v --print-estimate option to estimate the size of data that virt-v2v will copy.

       Virt-v2v is now usually able to remove open-vm-tools and VMware Tools from the Linux guest
       during conversion (Pino Toscano).

       Virt-v2v can now support UEFI conversions to RHV (Tomáš Golembiovský).

       Virt-p2v now prefers you to shut down instead of rebooting the machine after conversion
       has finished (Pino Toscano).

       Virt-v2v now writes the libosinfo short ID to the libvirt metadata when using -o local and
       -o libvirt output modes (Martin Kletzander).

       Language bindings

       OpenJDK 10+ is supported (Pino Toscano).

       Java bindings fixed for Gentoo host (Martin Kletzander).

       Inspection

       Support Kali Linux (Pino Toscano).

       When inspecting mountpoints, look for /etc/mdadm/mdadm.conf as well as /etc/mdadm.conf
       (Nikolay Ivanets).

       Improved support for OpenSUSE Tumbleweed (Pino Toscano).

       Architectures and platforms

       Miscellaneous macOS build fixes (Adam Robinson).

       Other

       Multiple documentation typos fixed (Yuri Chornoivan).

   Security
       See also guestfs-security(1).

       CVE-2018-11806

       Qemu's slirp (userspace networking) had several buffer overflows which could be triggered
       from the guest or network side.

   API
       New APIs

       "f2fs_expand"
           Expand an f2fs filesystem (Pino Toscano).

       "inspect_get_osinfo"
           Get the libosinfo short ID for the inspected guest (Pino Toscano).

       "lvm_scan"
           This rescans all PVs, VGs and LVs, optionally activating them.

       Other API changes

       "part_get_mbr_part_type" was reimplemented in OCaml (Nikolay Ivanets).

       "list_filesystems" now filters out MBR extended partitions (Nikolay Ivanets).

       "vgscan" has been deprecated.  Use the new "lvm_scan" API in preference.

   Build changes
       The JSON library switched from yajl to Jansson ≥ 2.7 (Pino Toscano).

       Support for The Sleuth Kit 4.5 (Pino Toscano).

       Multiple improvements in the "./configure" script (Lin Ma).

       More out-of-tree build fixes (Hilko Bengen).

       Some work on reproducible builds (Bernhard M. Wiedemann).

   内部
       lvmetad is now used unconditionally, and is started much earlier in the appliance boot
       process.  This fixes support for certain PV types.

       On Debian, dash is installed inside the appliance and in virt-rescue (Pino Toscano).

       The amount of RAM assigned to the appliance has been increased from 500M to 768M (on
       x86_64, other architectures have different limits).  This enables use of up to 255 disks
       when using recent Linux kernels.

       Virt-v2v now models the source machine type (eg. i440FX, Q35 or virt).

       Virt-p2v now generates configuration code automatically, also code for parsing the kernel
       command line.

       Use "LT_INIT" instead of "AC_PROG_LIBTOOL".

       The OCaml "JSON" code for parsing and serializing has been unified into a single abstract
       data type.

       Most OCaml tools are now built using the PIC runtime.  This has a performance penalty on
       i686, but is relatively free on other architectures and has security benefits.

       The direct backend now queries the qemu binary for availability of KVM, instead of using a
       heuristic based on /dev/kvm (Andrea Bolognani).

       Our "clever" libxml2 writer macros are now used consistently across all parts of the code
       base.

       Qemu dropped -nodefconfig without telling us.  The equivalent -no-user-config option is
       now used instead.  Qemu also moved the "serial" option from -drive to -device, again
       without any notice, and this is also fixed.

RELEASE NOTES FOR LIBGUESTFS 1.38

       These release notes only cover the differences from the previous stable/dev branch split
       (1.36.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       New tools

       Virt-builder-repository is a new tool allowing end users to create and update virt-builder
       repositories (Cédric Bosdonnat).

       Virt-rescue (while not a new tool) has been substantially rewritten, implementing job
       control, -m and -i options, escape keys, etc.

       New features in existing tools

       Virt-builder planner has been improved so that faster and more efficient build plans are
       chosen for complex cases, especially when either the tmpdir or output is on networked
       storage.

       New virt-builder Fedora templates (starting with Fedora 26) will have plain partition
       layout and use GPT for partitions.

       Virt-customize "firstboot" scripts in guests using systemd are now installed under the
       "multi-user.target" instead of "default.target" so they will only run when the system is
       booted normally.

       Virt-customize now sets a random /etc/machine-id for Linux guests, if one is not already
       set.

       Virt-df now works correctly on filesystems with block sizes smaller than 1K (Nikolay
       Ivanets).

       Virt-dib has further compatibility enhancements with diskimage-builder (Pino Toscano).

       Virt-sysprep removes "DHCP_HOSTNAME" from ifcfg-* files.

       Virt-sysprep now works on Oracle Linux (Jamie Iles).

       Virt-resize now correctly copies GPT partition attributes from the source to the
       destination (Cédric Bosdonnat).

       Bash tab completion implemented or enhanced for: virt-win-reg, virt-v2v-copy-to-local.

       virt-v2v and virt-p2v

       Virt-v2v can now read VMware VMX files directly, either from local disk, NFS storage, or
       over SSH from an ESXi hypervisor.

       Virt-v2v can now use VDDK as an input source.

       Both virt-v2v and virt-p2v are now able to pass through the source CPU vendor, model and
       topology.  However unfortunately not all source and target hypervisors are able to provide
       or consume this data at present (Tomáš Golembiovský).

       Virt-v2v now supports encrypted guests (Pino Toscano).

       Virt-v2v can now handle VMware snapshots.  Note that the snapshots are collapsed — it does
       not convert the chain of snapshots into a chain of snapshots.

       Virt-v2v now installs Windows 10 / Windows Server 2016 virtio block drivers correctly
       (Pavel Butsykin, Kun Wei).

       Virt-v2v now installs virtio-rng, balloon and pvpanic drivers, and correctly sets this in
       the target hypervisor metadata for hypervisors which support that (Tomáš Golembiovský).

       Virt-v2v now installs both legacy and modern virtio keys in the Windows registry (Ladi
       Prosek).

       Virt-p2v can now preserve (in some cases) the offset of the Real Time Clock from UTC.

       Virt-p2v now combines several scp commands to the conversion server into a single command,
       improving conversion times.

       Virt-v2v now detects the special Linux Xen PV-only kernels correctly (Laszlo Ersek).

       Virt-v2v -o glance now generates the right properties for UEFI guests (Pino Toscano).

       Virt-v2v -o null now avoids spooling the guest to a temporary file, instead it writes to
       the qemu "null block device".  This makes it faster and use almost no disk space.

       Virt-v2v -o rhv now supports Windows 2016 Server guest type.

       Virt-v2v -i libvirtxml can now open network disks over http or https.

       Virt-v2v will now give a warning about host passthrough devices (Pino Toscano).

       The virt-v2v --machine-readable output has been enhanced so it includes "vcenter-https",
       "xen-ssh" and "in-place" facts (Pino Toscano).

       Language bindings

       Fix multiple memory leaks and other data corruption problems in the Java bindings (Pino
       Toscano).

       Perl %guestfs_introspection has been dropped.

       Inspection

       Inspection support was rewritten in OCaml and included inside the daemon.  This makes
       inspection considerably faster, more robust and more easily extensible in future.

       Better icon support for ALT Linux guests (Pino Toscano).

       Better support for NeoKylin (Qingzheng Zhang).

       Can handle OSes like Void Linux which do not include "VERSION_ID" in /etc/os-release (Pino
       Toscano).

       Add support for Microsoft MS-DOS (Daniel Berrangé).

       Architectures and platforms

       Multiple fixes for S/390 architecture.  Libguestfs and all the tools should now compile
       and run on this architecture.

       Other

       The libguestfs API is now thread-safe (although not parallel).  You can call APIs on the
       same handle from multiple threads without needing to take a lock.

   Security
       There were multiple vulnerabilities in the icoutils "wrestool" program which is run by
       libguestfs to create icons for Windows guests.  Using the latest "wrestool" is
       recommended.

   API
       New APIs

       "hivex_value_string"
           This replaces the deprecated "hivex_value_utf8" API, but does the same thing.

       "part_get_gpt_attributes"
       "part_set_gpt_attributes"
           Read and write GPT partition attribute flags (Cédric Bosdonnat).

       "part_resize"
           Enlarge or shrink an existing partition (Nikos Skalkotos).

       "yara_destroy"
       "yara_load"
       "yara_scan"
           Support for the Yara malware scanning engine (Matteo Cafasso).

       Other API changes

       APIs implemented in the daemon can now be written in either C or OCaml.  Several APIs were
       rewritten in OCaml, although we are not planning to rewrite all of them.

       You will now get a clear error message if you try to add too many disks to the appliance,
       instead of getting a peculiar failure from qemu.

       Certain APIs accidentally allowed you to use "/dev/urandom" as an input "device", eg.
       "g.copy_device_to_device("/dev/urandom", "/dev/sda")".  The code has been modified to
       forbid this usage.

       All APIs for inspecting installer CDs have been deprecated.  Use libosinfo for this task.

   Build changes
       A working OCaml compiler ≥ 4.01 is now required for building libguestfs.  The "./configure
       --disable-ocaml" option remains but is only used to disable the OCaml language bindings.

       Add "RELEASES" file which lists release dates for each version of libguestfs.  You must
       update this file when making a new release.

       Documentation generated by "gtk-doc" has been removed.  "./configure --enable-gtk-doc" now
       does nothing.

       Libtirpc is now used for XDR functions and rpcgen.  Note that glibc has deprecated and in
       most Linux distros dropped these, so for most people this will be an extra dependency
       (Martin Kletzander).

       Libxcrypt is now used for crypt(3).  This is required if using glibc ≥ 2.27.

       "ocaml-hivex" is now required.

       Libvirt ≥ 1.2.20 is now required.

       There is now a "make check-root" target for tests which need to be run as root (analogous
       to "make check-slow").

       "./configure"-time check for "__attribute__((cleanup))" now works in the cross-compilation
       case (Yann E. Morin).

       The "AUTHORS" and "p2v/about-authors.c" files are now generated from a single place.

       Either GnuPG v1 or v2 can be used.

       "./configure --with-guestfs-path" may be used to set the default "LIBGUESTFS_PATH".  In
       addition the way that the path is searched has changed slightly so that all types of
       appliances are searched in each path element separately (Pavel Butsykin).

       "GUESTFSD_EXT_CMD" which was used to mark external commands in the daemon has been
       removed.  It was originally used by SUSE builds, but they have not been using it for a
       while.

       The output from "./configure" is now visually grouped under headings related to what it is
       doing, making it much easier to scan (Pino Toscano).

       OCaml dependencies are now generated from a single script instead of multiple not-quite-
       the-same Makefile fragments.

       "./configure --with-distro=ID" can be used to override automatic Linux distro detection at
       build time (Pino Toscano).

       qemu ≥ 2.10 is supported (but not required).  This adds mandatory locking to disks and
       libguestfs turns this off in certain circumstances when it is known to be safe (Lars
       Seipel, Peter Krempa, Daniel Berrangé, Pino Toscano, Fam Zheng, Yongkui Guo, Václav
       Kadlčík).

   内部
       Most common code has been moved to the common/ subdirectory, with OCaml common code being
       in common/ml* directories (eg.  common/visit and common/mlvisit contain the visitor
       library in C and OCaml respectively).  The mllib directory has been deleted and replaced
       by common/mltools.

       There is now a lightweight OCaml binding for PCRE, see common/mlpcre.  Use of OCaml "Str"
       library has been mostly replaced with PCRE.

       Add more calls to "udev_settle" to improve stability of partition code (Dawid Zamirski).

       Run "udev_settle" with --exit-if-exists option, which improves the speed of this command
       (Pavel Butsykin).

       Detect new locations of major(3), minor(3), makedev(3).

       Actions can now be deprecated with no suggested replacement, for APIs such as
       "guestfs_wait_ready" that should simply be removed from client code.

       Use gnulib "set_nonblocking_flag" wrapper instead of calling fcntl(2) with "O_NONBLOCK"
       (Eric Blake).  Similarly "set_cloexec_flag".

       Fix memory leak in XFS version of "guestfs_vfs_minimum_size" (Pino Toscano).

       Valgrind checks now run on the virt-p2v binary.

       Unicode single quotes ("‘’") and now used in place of '' or `' throughout the code and
       documentation.  Similarly for "’s" instead of "'s".

       The "is_zero" function has been reimplemented for greater speed (Eric Blake).

       In the direct backend, virtio-blk support has been removed.  Virtio-scsi is now the only
       supported way to add disks.

       Generator string parameter and return types have been rationalised so there are only two
       types ("String", "StringList") with many subtypes eg. "FileIn" becomes "String (FileIn,
       ...)".

       The appliance disk image can now be in formats other than raw (Pavel Butsykin).

       Multiple improvements to how we automatically build Debian templates for virt-builder
       (Pino Toscano).  Enable serial console for these templates (Florian Klink).

       In the daemon, instead of making a private copy of lvm.conf and modifying it (eg for
       filters), start with an empty file since LVM understands that to mean "all defaults"
       (Alasdair Kergon, Zdenek Kabelac).

       The "direct" backend can now run QMP queries against the QEMU binary, enhancing the kinds
       of information we can detect.  In addition the code to query QEMU has been made more
       robust for handling multiple parallel queries of different versions of QEMU.

       OCaml Augeas bindings are bundled under common/mlaugeas.  The long term plan is to remove
       this and use system ocaml-augeas when it is more widely available in distros (Pino
       Toscano).

       All OCaml modules ("*.ml" files) are now required to have an interface file ("*.mli").  If
       they don't export anything then the interface will be empty except for comments.

       Certain OCaml features in OCaml ≥ 4.01 are used throughout the code, including replacing
       ‘{ field = field }’ with ‘{ field }’.

       Virt-builder "make-template" utility now uses the "virt-install --transient" option so
       that we should never need to clean up left over domains after a crash.  It also saves
       kickstarts and virt-install commands, which are committed to git for future reference.

       /dev/shm is now created in the appliance (Nicolas Hicher).

       In verbose mode on Fedora guests, virt-customize will now use "dnf --verbose" enabling
       better debugging output.

       Virt-v2v input and output classes now contain a "#precheck" method which is used to
       perform environmental checks before conversion starts.

       Virt-p2v enables miniexpect debugging.  It is written to stderr (of virt-p2v).

       Virt-v2v free space checks are more liberal especially for smaller guests (Pino Toscano).

RELEASE NOTES FOR LIBGUESTFS 1.36

       These release notes only cover the differences from the previous stable/dev branch split
       (1.34.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       New tools

       Virt-tail is a new tool for following (tailing) log files within a guest, similar to the
       regular "tail -f" command.

       New features in existing tools

       Virt-customize, virt-get-kernel, virt-sparsify and virt-sysprep can now handle encrypted
       guests (Pino Toscano).

       Virt-builder and virt-customize now support --append-line, which is useful for adding
       lines to the end of configuration files.

       Virt-resize can now shrink and expand swap partitions (Pino Toscano).

       Virt-resize can now output to non-local disks (Pino Toscano).

       Virt-sysprep has a new operation called "backup-files" for removing editor backups, and
       "passwd-backups" for removing /etc/passwd- and similar.

       Virt-dib can now create checksums using the new --checksum option (Pino Toscano).

       Virt-dib can now create tgz files.  In addition, extended attributes and SELinux labels
       are preserved in the output tar file (Pino Toscano).

       Virt-dib can now create squashfs files (Pino Toscano).

       Bash tab-completion is now available in every command line tool that is shipped.

       virt-v2v and virt-p2v

       Conversions of Debian (6+) and Ubuntu (10.04+) guests are now supported (Tomáš
       Golembiovský, Pino Toscano).

       Conversions from SUSE Xen hypervisor have now been tested (Cédric Bosdonnat).

       Windows conversions may now install a program "pnp_wait.exe" which prevents conflicts
       between the Windows Plug-and-Play Manager and our own scripts that install virtio device
       drivers.  Enabling this requires the "pnp_wait.exe" program to be built separately (Roman
       Kagan).

       OVA files exported from AWS can now be converted (Shahar Havivi).

       When converting OVA files, in some circumstances virt-v2v can now read disk images
       directly from the OVA input file instead of needing to unpack the OVA file to a temporary
       directory.  This can save large amounts of disk space, and is quicker (Tomáš
       Golembiovský).

       Virt-p2v can now be built on RHEL 5 (2007-era) Linux and RHEL 6, which means that 32 bit
       and hardware with ancient fakeraid disks can be virtualized.  Binaries of virt-p2v based
       on these old versions of RHEL can be found at http://oirase.annexia.org/virt-p2v/

       Virt-p2v can now use nbdkit (an NBD server) as an alternative to qemu-nbd.  In addition,
       virt-p2v can use "socket activation" which is a more robust method for opening the NBD
       listening socket.  Socket activation works with qemu-nbd or nbdkit, but requires the most
       up to date versions.

       To prevent timeouts during P2V conversions, virt-p2v inhibits power saving on the physical
       machine, and also sends ping packets over the ssh control and data connections.

       Virt-v2v no longer removes the "Processor" and "Intelppm" nodes from the Windows Registry.

       Xen and vCenter conversions can now be done using the libvirt backend, provided libvirt ≥
       2.1.0 is used.

       /dev/srX (SCSI CD-ROM) devices are ignored (Tomáš Golembiovský).

       When converting SUSE Linux guests, use /etc/modprobe.conf.local if it exists.

       Removing VMware tools from Linux guests should now work reliably (Pino Toscano).

       When converting OVA files, virt-v2v now checks the disk image hash contained in the
       manifest file, whereas previously it was ignored because of a mistake in the code.  In
       addition, SHA256 hashes are now supported (Tomáš Golembiovský).

       When converting OVA files that contain compressed disk images, we now trust the
       "ovf:compression" attribute from the metadata instead of using content sniffing on the
       disk image (Tomáš Golembiovský).

       A new flag --vdsm-compat has been added to -o vdsm mode, allowing more efficient qcow2
       images to be generated.

       Since the RHEV product [commercially supported version of oVirt] has now been renamed to
       RHV, "RHEV" was changed to "RHV" throughout the tooling.  In particular, -o rhev becomes
       -o rhv, although the old name can be used for backwards compatibility.

       The "RHEV-APT" utility is only installed when the output hypervisor is oVirt or RHV.

       A problem with virt-v2v running out of memory when doing an SELinux relabel of the guest
       filesystem should now be resolved.

       Language bindings

       Setting "EXTRA_JAVAC_FLAGS" before ./configure allows you to add arbitrary flags to
       "javac" when compiling the Java bindings.

       Use of any libguestfs API which returned a single struct, from Perl or Java bindings,
       would have leaked memory.  This has now been fixed (Pino Toscano).

       Inspection

       Inspection of Windows guests with mildly corrupted Windows Registry hives should now work
       instead of failing with an error.  This feature requires hivex ≥ 1.3.14 (Dawid Zamirski).

       For Debian guests, we can now read the URL, source name, summary and full description of
       installed packages.  For RPM-based guests we can read the URL, summary and description
       (Pino Toscano).

       Inspection of guest operating systems that use a separate /usr partition should now work
       more reliably (Pino Toscano).

       When parsing guest /etc/fstab, paths are reduced to a canonical form (eg.
       "///usr//local//" → "/usr/local").

       Inspection of btrfs subvolumes now works where the /etc/fstab options field contains
       commas.

       /dev/cdN devices in guest /etc/fstab are ignored (Pino Toscano).

       Architectures and platforms

       Stable releases are now tested on aarch64, ppc64 and ppc64le architectures.

       The RISC-V architecture is now handled as a guest, and libguestfs will now at least
       compile on RISC-V (but probably not work as there is no usable qemu at the time of
       writing).

       Detection of S/390 and S/390x binaries and guests is now supported.

       Other

       ExFAT filesystems are now supported (Miles Wolbe).

   Security
       See also guestfs-security(1).

       There were no CVEs reported in this development cycle.  However some security-related
       hardening was carried out as described below.

       Temporary filenames are now always generated using randomness from /dev/urandom
       (previously the C function random(3) was used in one case).

       The $TERM environment variable is now validated before passing it through to the appliance
       kernel command line.

   API
       New APIs

       "guestfs_aug_transform"
           Exposes the Augeas "aug_transform" API (Pino Toscano).

       "guestfs_find_inode"
           Find files by inode number (Matteo Cafasso).

       "guestfs_inspect_get_windows_software_hive"
       "guestfs_inspect_get_windows_system_hive"
           Return the path to the Windows "HKLM\SYSTEM" and "HKLM\SOFTWARE" hives computed during
           inspection.

       "guestfs_mksquashfs"
           Create a squashfs filesystem from a path (Pino Toscano).

       Other API changes

       "guestfs_add_domain"
           This call now handles libvirt file-based volumes correctly, where previously these
           would have been ignored.  Also handled are disks which require libvirt authentication
           secrets to open (Pino Toscano).

       "guestfs_canonical_device_name"
           This call will no longer incorrectly modify Linux software RAID device names (like
           /dev/mdX).

       "guestfs_file_architecture"
           Previously the "file_architecture" API could return either of the strings "i386" or
           "i486" for 32 bit x86 binaries.  It now only returns "i386" (as documented).

           This API can now return the following new values: "riscv32", "riscv64", "riscv128",
           "s390", "s390x".

       "guestfs_hivex_open"
           This now has an optional "GUESTFS_HIVEX_OPEN_UNSAFE" flag which allows certain
           corrupted Windows Registry hives to be opened.  This feature requires hivex ≥ 1.3.14
           (Dawid Zamirski).

       "guestfs_list_partitions"
           This call now returns Linux software RAID partitions.

       "guestfs_part_to_dev"
           This call now correctly handles partition names which include "p<N>" (Pino Toscano).

       "guestfs_set_label"
           This call can now change the labels of swap partitions (Pino Toscano).

   Build changes
       libmagic, the library part of the "file" command, is now required at build time
       (previously optional).

       GCC 7 is now supported.

       "Silent rules" are now used for OCaml programs, Java bindings.  To show the full command
       line executed, add "V=1" on the make command line (Pino Toscano).

       Slow testing ("make check-slow") now covers: firstboot scripts in Linux guests; v2v
       conversion of a selection of real Linux guests; the virt-customize --hostname and
       --timezone settings; the --root-password parameter; that the serial console works in virt-
       builder guests.

       Large generated C source files, eg. the list of commands found in fish/cmds.c (and many
       more), have been split into smaller files to speed parallel compilation.

       "make maintainer-check-extra-dist" now checks that all generated files are included in the
       tarball.

       The tests no longer assume that "." is in Perl's @INC, as it is going to be removed soon
       (Pino Toscano).

       Debian hosts using UsrMerge are now supported (Pino Toscano).

       Header files and C structs can now have internal documentation using the special "/** ...
       */" comments.

       "@VAR@" subtitutions in "./run" are now fully quoted.  This is necessary so that (eg)
       "./configure PYTHON=/some/path" works robustly if "/some/path" contains characters that
       need to be quoted (Hilko Bengen).

       gperf ≥ 3.1 is now supported.

       Kraxel's old edk2 builds can no longer be used for UEFI support.  UEFI code is now fully
       free software, so use the versions bundled with your Linux distro instead.

       Virt-p2v can now be compiled on RHEL 5 (2007-era) Linux with Gtk 2.10.

   内部
       The generator and mllib "Common_utils" modules are now shared from the same source file.

       A considerable amount of common code has been moved into the common directory in the
       source and is now compiled only once.  The mini-libraries located under here are:
       common/edit, common/errnostring, common/miniexpect, common/options, common/parallel,
       common/progress, common/protocol, common/utils, common/visit, common/windows.

       The directory containing the main library code has moved from srclib.

       All tests written in shell script now use a common file of utility functions
       (tests/test-functions.sh).  There are several new utility functions, mainly for skipping
       tests.  Also these test scripts can now use autoconf-like path variables like
       $abs_top_srcdir.

       UEFI paths are now stored in the generator (generator/uefi.ml).

       The way the generator handles actions and procedure numbers was changed quite
       substantially.  See generator/actions_*.ml and generator/proc_nr.ml.

       The gnulib "getprogname" module is now used everywhere when needing/printing the program
       name (Pino Toscano).

       perl/Guestfs.c is not translatable (Nikos Skalkotos).

       Virt-builder templates moved from builder/website to builder/templates and there is now a
       single unified program which can build any template.

       All Windows registry utilities used by virt-customize and virt-v2v have been moved to a
       common module called "Registry" under mllib.

       All POSIX bindings have been moved to a new module called "Unix_utils" under mllib.

       Inspection, virt-customize and virt-v2v no longer recompute the Windows "%systemroot%",
       "CurrentControlSet" or paths to the "HKLM\SYSTEM" and "HKLM\SOFTWARE" hives in multiple
       places.  Instead these are all computed once (during inspection) and passed to the other
       tools through various "guestfs_inspect_get_windows_*" APIs.

       "/dev/pts" is now available inside the appliance, so any tools we run which require a pty
       will now work (Pino Toscano).

       Most OCaml warnings have been fixed.

       There is now a single common function for creating temporary files
       ("guestfs_int_make_temp_path") (Matteo Cafasso).

       The $TERM environment variable is now validated before passing it through to the appliance
       kernel command line.

       Useless USB and memballoon devices are no longer created in the appliance (Laine Stump).

       On aarch64 we now use virtio-pci for the appliance.  This is somewhat faster than virtio-
       mmio.

       Use of srandom(3) and random(3) has been minimized.  In particular, temporary filenames
       are no longer created based on randomness returned by random(3), but /dev/urandom is used
       instead.

RELEASE NOTES FOR LIBGUESTFS 1.34

       These release notes only cover the differences from the previous stable/dev branch split
       (1.32.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       Multiple performance enhancements were made in libguestfs.  The "hot cache" time to launch
       to appliance should be under 1 second assuming recent qemu and kernel are installed.
       There are also new utilities for precisely benchmarking libguestfs (utils/boot-benchmark
       and utils/boot-analysis in the source tree).

       The virt-p2v tool for converting physical machines to virtual machines was substantially
       improved.  This includes: clearer, coloured output during conversions, support for Gtk 3,
       more detailed information about hardware, click to identify network interfaces, more
       debugging tools included with the ISO, and many bug fixes.

       f2fs (Flash Friendly File System) is now supported (Pino Toscano).

       New tools

       virt-p2v-make-kiwi(1) can be used to build the virt-p2v ISO based on SLES and openSUSE,
       using the kiwi utility (Cédric Bosdonnat).

       New features in existing tools

       virt-resize will now preserve the GPT GUID.  This was required for Windows Server 2012 R2,
       where the bootloader would become confused if the GUID changed (Maxim Perevedentsev).

       virt-resize will use sparse copying for (old MBR-style) extended partitions.  This makes
       resizing of guests that use extended partitions much faster (Maxim Perevedentsev).

       virt-p2v kernel command line options can now be used to set defaults for GUI
       configuration.

       The virt-p2v debugging options have been completely removed, simplifying the interface and
       documentation.  Debugging information is now captured fully automatically.

       virt-p2v-make-disk lets you specify an --arch option, allowing you to build a 32 bit
       virt-p2v, for compatibility with older systems.

       virt-p2v-make-disk no longer requires that you specify an "os-version" for the virt-p2v
       disk.  If omitted it will try to choose a suitable "os-version" depending on your host
       system.

       virt-p2v-make-disk and virt-p2v-make-kickstart both gain a new --install option that
       allows you to add arbitrary extra packages to the virt-p2v ISO, for customization,
       additional debugging tools and so on.

       virt-v2v will now uninstall Parallels Tools (or the equivalent Virtuozzo Tools) from Linux
       guests.  Also stop the Windows drivers from loading at boot.  (Roman Kagan and Pavel
       Butsykin)

       virt-v2v --in-place mode has been enhanced to allow the caller to choose whether or not to
       install certain virtio drivers in the guest (Roman Kagan).

       virt-v2v conversion of Windows guests was substantially rewritten and simplified (Roman
       Kagan).

       virt-v2v --in-place mode now supports installing virtio-scsi drivers in guests (Roman
       Kagan).

       virt-v2v can now convert SUSE guests and SUSE guests using UEFI (Cédric Bosdonnat and Jim
       Fehlig).

       virt-v2v can now convert guests to Glance that have multiple disks.  Previously it would
       fail on such guests.

       The virt-v2v --no-trim and --vmtype options are now no-ops.  They will print a warning but
       are otherwise ignored.  virt-v2v can now generate the OVF vmtype correctly without user
       intervention.

       virt-v2v has now been tested against SUSE Xen as a source hypervisor (Cédric Bosdonnat).

       virt-v2v adds support for SUSE VMDP drivers (Cédric Bosdonnat).

       virt-v2v can convert OVA files containing subfolders, as produced by SUSE Studio (Cédric
       Bosdonnat).

       virt-v2v sets the OVF "<Origin>" element correctly.  oVirt has been extended to support
       more source hypervisors (Shahar Havivi).

       virt-v2v now supports Windows Server 2016 (Tomáš Golembiovský).

       The virt-builder --list option can now be used to show all templates or a single template
       (Pino Toscano).

       All OCaml-based tools now use getopt_long(3) for option parsing, and --help output has
       been improved (Pino Toscano).

       virt-builder and virt-customize --selinux-relabel option can now fully relabel the guest
       filesystem at build time, without requiring a lengthy autorelabel at first boot.

       virt-customize --delete now accepts globs.

       New virt-customize --uninstall option lets you uninstall packages.

       virt-customize can now use "pvvxsvc" as an alternative to "rhsrvany" for running firstboot
       scripts in Windows guests (Cédric Bosdonnat).

       virt-customize now uses the strongest hashing scheme for passwords on Arch and Void Linux
       (Pino Toscano).

       virt-customize --install now works correctly on Arch (Pino Toscano).

       virt-inspector has new options --no-applications and --no-icon to prevent the list of
       applications and icon from being included in the XML output (Pino Toscano).

       New virt-sysprep --network option has been added, allowing you to actually use the
       --install etc options which were present in virt-sysprep before but did not usually work.
       Note that the network is still disabled by default.

       virt-sysprep "fs-uuids" operation no longer fails on btrfs guests (Maxim Perevedentsev).

       virt-dib can output Docker images (Pino Toscano).

       virt-dib has a new --drive-format option to allow the user to specify the format of the
       helper drive (Pino Toscano).

       All OCaml virt tools now have a --colors/--colours option which enables coloured output
       (using ANSI escape sequences) even if the output is not a tty.  The default is to check if
       the output is a tty and disable coloured output if not.  This allows coloured output to be
       consumed by other tools.

       Language bindings

       PHP test coverage has been enhanced (Pino Toscano).

       PHP 7 is now supported (Pino Toscano).

       Python bindings are now compliant with PEP 8 (Pino Toscano).

       A Python pip package is available in http://libguestfs.org/download/python/

       The Ruby bindings now print the full exception if one is thrown by the event callback.
       Note this is still incorrect behaviour as event callbacks should not throw exceptions, but
       it aids debugging.

       All OCaml libraries and programs are now compiled with -safe-string, if supported by the
       OCaml compiler.

       Inspection

       Alpine Linux using busybox can now be inspected.  Also the APK package manager is
       supported in virt-customize (Pino Toscano).

       We now handle inspection of Mageia 4 (Pino Toscano).

       Void Linux and the Void Linux xbps package manager are fully supported (Pino Toscano).

       Parsing of CoreOS version information has been enhanced (Pino Toscano).

       It is now possible to get an icon from ALT Linux (Pino Toscano).

       PLD Linux versions < 3 are now recognized (Pino Toscano).

       Windows drive letters are now returned for guests using GPT partitions (Dawid Zamirski).

       We can now correctly inspect Unix guests that do not have an /etc/fstab file (Pino
       Toscano).

       Added another source for the Ubuntu icon which doesn't rely on GNOME having been installed
       in the guest.

       We can now get an icon for Windows 7 64 bit guests.

       Libosinfo integration was rewritten to deal with the new database format used by osinfo
       (Pino Toscano).

       Documentation

       New manual page guestfs-building(1) describes how to build libguestfs from source.

       The man pages, tools and tool --help output is now automatically checked to ensure that
       all tool options are properly documented, that warning sections are included where
       necessary, and that every page has a description section.

       The guestfs-testing(1) man page has been refreshed and based on a newer libguestfs.

       Architectures and platforms

       virt-customize now works on POWER7 and POWER8 platforms, both big endian and little endian
       (Xianghua Chen and Hu Zhang).

   Security
       See also guestfs-security(1).

       CVE-2015-8869

       https://bugzilla.redhat.com/CVE-2015-8869

       This vulnerability in OCaml might affect virt tools written in the OCaml programming
       language.  It affects only 64 bit platforms.  Because this bug affects code generation it
       is difficult to predict which precise software could be affected, and therefore our
       recommendation is that you recompile libguestfs using a version of the OCaml compiler
       where this bug has been fixed (or ask your Linux distro to do the same).

       virt-customize ownership of .ssh, .ssh/authorized_keys

       https://bugzilla.redhat.com/1337561

       Previously when virt-customize injected an SSH key into a guest, when it created the
       ~/.ssh and ~/.ssh/authorized_keys directory and file (in case they were missing) it
       created them with owner and group "root.root".  This has been fixed so the correct user is
       used.  This is not thought to have been exploitable.

       Windows "%systemroot%"

       The inspection code has been made more robust against guests which might use very long
       "%systemroot%" (derived from the guest-controlled Windows Registry).  This is not thought
       to have been exploitable.

       Virtio-rng is now available in the appliance

       virtio-rng (the virtual Random Number Generator device) is now passed to the appliance,
       which should improve the quality random numbers generated for GUIDs and cryptographic key
       generation.

   API
       New APIs

       "btrfs_filesystem_show"
           List all devices where a btrfs filesystem is spanned (Pino Toscano).

       "download_blocks"
       "download_inode"
       "filesystem_walk"
           Download filesystem data blocks from a given partition.  Download arbitrary files by
           inode number.  Retrieve all files from a filesystem including deleted files.

           Note these require optional dependency The Sleuth Kit.  (Matteo Cafasso)

       "get_sockdir"
           Read the path where temporary sockets are stored (Pino Toscano).

       "mountable_device"
       "mountable_subvolume"
           Split a Mountable into device name and subvolume (Cédric Bosdonnat).

       "ntfscat_i"
           Download NTFS file by inode number (Matteo Cafasso).

       "part_expand_gpt"
           Allow in-place expanding of GPT partitions by moving the second (backup) partition
           table to the end of the disk (Maxim Perevedentsev).

       "part_get_disk_guid"
       "part_set_disk_guid"
       "part_set_disk_guid_random"
           Get and set the GPT disk GUID, or set it to a fresh random value (Maxim
           Perevedentsev).

       "selinux_relabel"
           SELinux-relabel part or all of the guest filesystem.

       Other API changes

       "guestfs_set_selinux", "guestfs_get_selinux", "guestfs_setcon", "guestfs_getcon" and
       "guestfs_llz" have been deprecated.  Use the new API "guestfs_selinux_relabel" to relabel
       filesystems.  Use "guestfs_lgetxattrs" to list the "security.selinux" extended attributes
       of existing files.

       "guestfs_vfs_minimum_size" can now be used on dirty filesystems (Maxim Perevedentsev).

       "guestfs_ll" now works on paths which contain absolute symlinks (Pino Toscano).

       "guestfs_glob_expand" now has an optional "directoryslash" boolean parameter which
       controls whether trailing slashes are returned for directory names (Pino Toscano).

       "guestfs_lvs" will no longer return LVs which have the "activationskip" flag set.  The
       reason is that such LVs have no "/dev/VG/LV" device node and so code which read the list
       of LVs and then probed the devices themselves would immediately fail.  You can use
       "guestfs_lvs_full" if you want to read all LVs.  (Pino Toscano).

       "guestfs_list_disk_labels" now no longer fails if no disks with labels were added.
       Instead it now returns an empty list (Pino Toscano).

       "guestfs_is_lv" no longer fails if passed a btrfs subvolume, it returns false instead
       (Maxim Perevedentsev).

   Build changes
       qemu ≥ 1.3.0 is required.

       yajl (a JSON parsing library) is required to build libguestfs.

       You can now build with GCC 6.

       "make check-valgrind" now has substantially better coverage.

       "make check-slow" now works again.

       Use "make -C appliance clean-supermin-appliance" to clean the supermin appliance (it will
       be rebuilt on next "make").

       There are a variety of new rules for running virt-p2v from the source directory: "make -C
       p2v run-virt-p2v-directly" | "run-virt-p2v-in-a-vm" | "run-virt-p2v-non-gui-conversion".
       These are documented further in guestfs-hacking(1).

       virt-p2v may be built using either Gtk 2 or Gtk 3.  To force a particular version of Gtk
       to be used, "./configure --with-gtk=2|3"

       The "./configure" options are now mostly documented in guestfs-building(1).

   内部
       In git, versions are now tagged with "v1.XX.YY" (previously they were tagged with
       "1.XX.YY").  Using the "v-" prefix is more common in git repositories.

       When using the libvirt backend, we now wait for qemu to exit gracefully instead of killing
       it after 15 seconds.  This helps when writing to slow devices (especially cheap USB keys).

       Error messages from libvirt now include the "err->int1" field which usually contains the
       "errno".

       On ARM, all DTB (device tree) code has been removed.  qemu creates the right device tree
       on the fly, we do not need to specify one.

       The C API tests now use larger test disks, allowing BTRFS to be tested properly (Pino
       Toscano).

       The tests should now work on a pure Python 3 host (Pino Toscano).

       In C bindings, internal functions are now (mostly) consistently named "guestfs_int_*"
       whereas previously there was no consistent scheme.

       The old "safe_malloc" etc functions are now no longer exported by the library, nor used in
       language bindings.

       Setting TMPDIR to a path longer than ~ 100 characters will no longer cause libguestfs to
       fail silently and randomly when creating Unix domain sockets (Pino Toscano).

       The "COMPILE_REGEXP" macro can now be used in the daemon.

       When tracing, results containing structs are now printed in full (Pino Toscano).

       The Perl "Sys::Guestfs" module now no longer embeds an incrementing API "version number".
       This module is now always at phony version "1.0".  To find the real version of libguestfs
       from Perl you must call "$g->version".

       All code is compiled with "-Wstack-usage=10000" and multiple changes have been made to
       remove stack allocation of large strings and buffers.

       The error(3) function is now used everywhere, replacing most previous uses of perror(3) +
       exit(3), and fprintf(3) + exit.

       In C code, "/**" comments are turned into documentation which is automatically added to
       the guestfs-hacking(1) manual page.

       A safe "getumask" function has been added.  For recent Linux kernels this uses the newly
       added "Umask" field in /proc/self/status.  For older Linux and other Unix, this uses a
       thread-safe technique involving fork(2) (thanks: Josh Stone, Jiri Jaburek, Eric Blake).

       Safe posix_fadvise(2) wrappers have been added, and more hints have been added to the code
       which may make a minor difference to performance.

       A safe wrapper around waitpid(2) has been added which handles "INTR" properly.

       "podwrapper.pl" (used to generate the manual pages) now stops if any POD error is found.
       A new script called "podcheck.pl" does cross-checking of --help output, tool options and
       manual pages.

       All version numbers in the library (eg. versions of qemu, versions of libvirt, versions of
       guest operating systems) are unified in a single file src/version.c (Pino Toscano).

       On Windows guests, virt-customize will use the vendor-neutral path
       "C:\Program Files\Guestfs\Firstboot" to store firstboot scripts.  Previously it used
       "C:\Program Files\Red Hat\Firstboot".  This change should be invisible to the scripts
       themselves.  (Cédric Bosdonnat)

       On Linux guests, the firstboot services generated by virt-builder --firstboot etc have
       been renamed to "guestfs-firstboot" (Pino Toscano).

       There is now a common "debug" function used by all OCaml tools, replacing previous code
       which did "if verbose () then printf ...".

       virt-p2v copies files it needs over to the virt-v2v conversion server using scp(1),
       instead of trying to send them via the shell session.  This should improve reliability and
       should be a completely transparent to end users.

       All code in mllib is now built into a single "mllib.cma" or "mllib.cmxa" library.  All
       code in customize is now built into a single "customize.cma" or "customize.cmxa" library.
       This simplifies the build of the OCaml tools.

       lvmetad(8) is now used in the appliance when available (Pino Toscano).

       "Silent rules" are used for OCaml, Java, Erlang and POD.  Use "make V=1" to see the full
       command lines again (Pino Toscano).

RELEASE NOTES FOR LIBGUESTFS 1.32

       These release notes only cover the differences from the previous stable/dev branch split
       (1.30.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       New tools

       The new virt-v2v-copy-to-local(1) tool is an ancillary tool for virt-v2v(1) allowing you
       to convert source guests that virt-v2v is unable to access directly.

       New features in existing tools

       Virt-customize knows how to write a random seed to CirrOS (Pino Toscano).

       On Fedora, virt-customize runs dnf(8) with the --best flag, ensuring it always updates to
       the latest available packages.

       Virt-builder now provides 32 bit Fedora templates.

       Virt-builder and virt-customize --install option now works on 32 bit Fedora guests.
       Previously it would try to install 64 bit packages (Jan Sedlák).

       Virt-builder can now fetch cloud images using Simple Streams v1.0 metadata (Pino Toscano).

       Virt-builder can now fetch openSUSE cloud images out of the box (Cédric Bosdonnat).

       Virt-customize will now use stronger (SHA-512) encrypted passwords by default on openSUSE
       ≥ 11 (Pino Toscano).

       Virt-builder will now correctly handle output filenames containing colon characters (":"),
       and will create temporary files in the libguestfs cache directory instead of defaulting to
       /tmp (Pino Toscano).

       Virt-resize has a new --unknown-filesystems option to control what to do when asked to
       resize a filesystem that libguestfs doesn't know how to resize.

       Virt-v2v now has an --in-place flag/mode, allowing in-place conversion of guests (Roman
       Kagan).

       Virt-v2v has a --compressed option for creating compressed qcow2 output files.

       Virt-v2v can now correctly get the VMware datacenter path (dcPath)  from libvirt, instead
       of having to calculate it using an algorithm that occasionally got the wrong answer
       (Matthias Bolte, Tingting Zheng).

       Virt-v2v now processes RAM sizes correctly for 64 bit guests when running on a 32 bit
       host.

       Language bindings

       In Perl and Python programs, the "get_program_name" API now returns the true program name,
       instead of the incorrect string "perl" or "python".

       The Python bindings can now be compiled against a different version of libguestfs,
       allowing the pip module to be built against any version of libguestfs (instead of
       requiring the pip module and libguestfs to have exactly the same version).

       The quality of the Ruby rdoc (documentation) has been improved (Pino Toscano).

       Perl scripts no longer hard-code the location of perl in the shebang line, but use env(1)
       to locate it instead (Pino Toscano).

       In OCaml programs, the guestfs handle was incorrectly made into a global root, meaning it
       could never be garbage collected.  If you didn't call the "close" function explicitly, the
       handle would not be closed until the whole program exited.  This has now been fixed so
       handles will be garbage collected in the usual way.  This changes the API of the OCaml
       function "Guestfs.event_callback".  Note that non-C language bindings are not covered by
       the libguestfs API/ABI guarantee, although we try hard not to change them, but in this
       case it was essential in order to fix this very serious bug.

       Inspection

       Alpine Linux and the APK package manager, ALT Linux, Frugalware, and PLD Linux are now
       recognized (Pino Toscano).

       If it exists, /etc/os-release will be preferred for inspecting Linux guests (Pino
       Toscano).

       The correct kernel version is returned for Windows guests ≥ 10.

       Documentation

       The large guestfs(3) man page has been split into several separate man pages:
       guestfs-hacking(1) guestfs-internals(1) guestfs-security(1).  In the source tree, a new
       docs directory contains this documentation.

       Architectures and platforms

       Libguestfs now supports ARM 64 bit platforms with vGICv3.

   Security
       See also guestfs-security(1).

       "CVE-2015-5745"
           https://bugzilla.redhat.com/1251157

           This is not a vulnerability in libguestfs, but because we always give a virtio-serial
           port to each guest (since that is how guest-host communication happens), an escalation
           from the appliance to the host qemu process is possible.  This could affect you if:

           ·   your libguestfs program runs untrusted programs out of the guest (using
               "guestfs_sh" etc), or

           ·   another exploit was found in (for example) kernel filesystem code that allowed a
               malformed filesystem to take over the appliance.

           If you use sVirt to confine qemu, that would thwart some attacks.

       Virt-customize permissions on .ssh, .ssh/authorized_keys
           https://bugzilla.redhat.com/1260778.

           Previously when asked to inject an SSH key into a guest, virt-customize (hence virt-
           builder too) would create the .ssh directory and .ssh/authorized_keys file with too
           broad permissions, allowing other users to read.  They are now created as 0700 and
           0600 respectively, which is the same as the ssh-copy-id(1) utility.

   API
       New APIs

       "guestfs_get_identifier"
       "guestfs_set_identifier"
           Get/set a per-handle identifier.  The main effect of this is to change trace output
           from:

            libguestfs: trace: foo

           to:

            libguestfs: trace: ID: foo

           making it easier to follow traces in multi-threaded programs, or where a program uses
           multiple handles (especially virt-v2v).

       "guestfs_vfs_minimum_size"
           Return the minimum size of a filesystem (when shrunk).  This supports ext2/3/4, XFS
           and btrfs, and can support other filesystem types in future (Maxim Perevedentsev).

       Other API changes

       "guestfs_disk_create": add "preallocation" = "off"/"metadata"/"full".
           For raw, this allows "off" as a synonym for "sparse" (making it consistent with
           qcow2).  For qcow2, this allows "sparse" as a synonym for "off".

           It also adds "full", which corresponds to fully allocated, but uses posix_fallocate(3)
           for efficiency.

       "guestfs_tar_in": new "xattrs", "selinux", "acl" parameters.
       "guestfs_tar_out": new "xattrs", "selinux", "acl" parameters.
           These extra parameters control whether extended attributes, SELinux contexts and/or
           POSIX ACLs are restored from / saved to tarballs.

       "guestfs_add_drive"
           The existing "username" and "secret" parameters can be used to supply authentication
           for iSCSI (Pino Toscano).

   Build changes
       The "./configure --enable-valgrind-daemon" option has been removed.

       You can no longer build libguestfs on RHEL 5-era (c.2007) machines.  See the "oldlinux"
       branch if you need (limited) RHEL 5 support.

       Virt-p2v can now be built on RHEL 6-era (c.2010) Linux distros.

       OCaml ≥ 3.11 (released in 2008) is now required to build from git.

       Building the Perl bindings now requires "Module::Build" (instead of
       "ExtUtils::MakeMaker").

       Builds should be faster (especially when incrementally rebuilding), because work was done
       to reduce build times.

       Both OCaml and the OCaml findlib module are required if you need to run the generator at
       build time.  Previously the build would have failed if findlib was not installed.

       "make check" tests now run in parallel (within each test directory).

       "make install" no longer installs OCaml bindtests.* files incorrectly.

       "make install" can now be run twice.  Previously it would fail on the second run.

       "make clean" should now remove nearly every file that "make" creates.

       A new "make installcheck" rule has been added, allowing the installed copy of libguestfs
       to be tested.

   内部
       Some effort was put into minimizing the size of the appliance, which reduces temporary
       disk space and time needed by libguestfs handles.

       The appliance now passes the NIC name to dhcpd, fixing hangs when running the appliance on
       some distros (Cédric Bosdonnat).

       OCaml "Guestfs.Errno" is now generated (Pino Toscano).

       In OCaml tools, common code now handles --debug-gc, --verbose and other common options
       (Roman Kagan, Pino Toscano).

       The virt-v2v test harness allows us to boot the test guests at fixed dates in the past,
       ensuring that Windows reactivation doesn't kick in.

       There is a new internal API for reading/writing a subprocess via a pipe from library code.

       Used "deheader" program to remove unused "#include" directives.

       In OCaml tools, the "Char" and "String" modules now implicitly reference the
       "Common_utils.Char" and "Common_utils.String" modules (instead of the ones from stdlib).
       The "Common_utils" modules contain a number of extra char/string utility functions, and
       also hide some unsafe functions in stdlib.

       Many more virt-v2v tests will now be run even if you don't have rhsrvany and virtio-win
       installed (Roman Kagan).

       The huge configure.ac file has been split into several smaller files called
       m4/guestfs_*.m4.

       The old tests/data and tests/guests directories have been moved to test-data/.  This new
       top level directory carries all test data which is common, large and/or shared between
       multiple tests.

       There is a new top level website/ directory containing the public http://libguestfs.org
       website (or most of it).

       The fuzz testing of inspection (tests/fuzz) has been removed.

       Virt-p2v now saves the source physical machine dmesg output into the conversion server
       debug directory, making it simpler to debug cases of missing drivers, firmware etc.

RELEASE NOTES FOR LIBGUESTFS 1.30

       These release notes only cover the differences from the previous stable/dev branch split
       (1.28.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       New tools

       virt-dib(1) is a secure and safe alternative to the OpenStack "diskimage-builder" tool.
       It is compatible with diskimage-builder elements.  (Pino Toscano)

       virt-get-kernel(1) extracts the kernel and ramdisk from a disk image.  Previously this
       functionality was part of virt-builder(1), but the new tool is more featureful.  (Pino
       Toscano)

       New features in existing tools

       virt-v2v(1) -i ova mode can now read a wider range of OVA files, and also unpacked files
       (directories).

       virt-v2v now securely passes options to curl, so passwords, cookies and so on cannot be
       seen by users with shell access on the same machine.

       virt-v2v has a new --password-file option to allow you to securely pass in a password, and
       to avoid an interactive prompt.

       virt-v2v disables Windows autoreboot, making debugging conversion failures on Windows
       easier.

       virt-v2v now comes with an extensive external test suite.  See virt-v2v-test-harness(1).

       virt-v2v allows virtio drivers to come from any location (Roman Kagan), and drivers can be
       read directly from the virtio ISO.

       virt-v2v supports conversion of Windows ≥ 8.  Note this is experimental, and possibly
       broken.  Use with caution.

       virt-v2v can now convert UEFI guests.

       virt-p2v(1) adds a network configuration dialog.

       virt-p2v now has "p2v.pre", "p2v.post" and "p2v.fail" triggers, allowing arbitrary scripts
       for preparing the host for conversion and tidying up post-conversion.

       virt-p2v now uses the more advanced metacity window manager (instead of matchbox).

       virt-sysprep(1) will remove "/var/spool/mail/username" for non-root accounts (Hu Tao).

       virt-customize(1), virt-builder(1) and virt-sysprep have the following new options:

       --commands-from-file
           allow long lists of commands to be read from a file instead of from the command line
           (Pino Toscano)

       --copy
           copy files inside the guest (Maros Zatko)

       --copy-in
           copy host files recursively into the guest (Pino Toscano)

       --move
           move files inside the guest (Maros Zatko)

       --ssh-inject
           inject SSH keys into a guest (Pino Toscano)

       --sm-attach
       --sm-credentials
       --sm-register
       --sm-remove
       --sm-unregister
           register and unregister a guest from subscription-manager (Pino Toscano)

       --touch
           touch a file in the guest (Pino Toscano)

       --truncate
       --truncate-recursive
           truncate files (Maros Zatko)

       Improvements to virt-customize firstboot support.  In particular, Windows firstboot should
       work as well as Linux (Roman Kagan).

       virt-df(1) can now use PolicyKit, SASL and other authentication methods when getting the
       list of domains from libvirt.

       Improvements to guestfish bash completion (Pino Toscano).

       Bash completion now completes short options as well as long options (Pino Toscano).

       guestfish(1) now displays a command synopsis if the number of parameters given to a
       command is wrong (Hu Tao).

       virt-builder now supports Red Hat Enterprise Linux versions back to RHEL 3.

       virt-builder supports SUSE guests using zypper (Cédric Bosdonnat).

       Language bindings

       The Java bindings now include validated Javadoc, and other improvements (Pino Toscano).

       Multiple fixes and improvements to the PHP bindings (Pino Toscano).

       Inspection

       Inspection can now get icons from RHEL 7 and CentOS 7.

       /etc/favicon.png is now allowed to be a symbolic link.

       For RPM-based guests, inspection now returns RPM Epoch fields.

       Debian packages now have separate Epoch and Version fields (Nikos Skalkotos).

       OpenBSD detection added, FreeBSD and NetBSD added as separate "distros", and other BSD
       inspection improvements and bug fixes (Nikos Skalkotos).

       CoreOS detection added (Nikos Skalkotos).

       The package manager in Fedora ≥ 22 is "dnf".

       ReactOS guests can be inspected (Maros Zatko).

       Add support for UEFI guests.

       Inspection now works when kernel modules are gzip or xz compressed (Pino Toscano).

       Inspection now recognizes ppc64 and ppc64le guests (Maros Zatko).

       Inspection lists the installed applications on Archlinux guests (Nikos Skalkotos).

       Architectures and platforms

       PPC64 (POWER7) and PPC64LE (POWER8) architectures are now much better supported, and
       should work out of the box.

       For aarch64, we use AAVMF (an open source UEFI implementation based on OVMF) if available
       to run the appliance.

       For armv7, we now use the -M virt machine type by default.

       There is better support for compiling on non-Linux platforms (Pino Toscano, Margaret
       Lewicka).

       Libguestfs should now work on MIPS 32 bit little endian ("mipsel").  I have not been able
       to try 64 bit or big endian.

   Security
       CVE-2014-8484
       CVE-2014-8485
           Libguestfs previously ran the strings(1) utility on untrusted files.  Strings could
           parse BFD headers in an unsafe way, leading to possible arbitrary code execution.
           Libguestfs now runs strings with a flag to ensure it does not try to parse BFD
           headers.  This could have led to exploitation of the libguestfs appliance, but since
           libguestfs further constrains the appliance through virtualization, SELinux and other
           techniques, it was unlikely to have caused any privilege escalation on the host.

       XPath injection in virt-v2v
           One possible XPath injection vulnerability was fixed in virt-v2v.  This might have
           allowed a malicious guest which was being converted by virt-v2v to construct an
           arbitrary XPath expression which would have been evaluated on the host (by the libxml2
           library linked to the virt-v2v binary).  It is not clear what the effects of this
           might be.

           For further information, see upstream commit
           https://github.com/libguestfs/libguestfs/commit/6c6ce85f94c36803fe2db35a98db436bff0c14b0

       Denial of service problems when using "qemu-img info"
           When using the American Fuzzy Lop fuzzer ("afl-fuzz") on the "qemu-img info" command,
           Richard W.M. Jones found that certain files can cause the "qemu-img" program to use
           lots of memory and time (for example 6GB of heap and 14 seconds of CPU time on a fast
           Intel processor), and in some cases to crash.  Since libguestfs may run "qemu-img
           info" on disk images to find out what they contain, this transitively could cause
           libguestfs to hang or consume lots of memory.

           Libguestfs was modified so that it uses resource limits to limit the space and time
           used by "qemu-img info", to avoid this problem.  If a malicious user tries to pass one
           of these disk images to libguestfs, "qemu-img" will crash and the crash is reported
           back to libguestfs callers as an error message.

   API
       New APIs

       "guestfs_add_libvirt_dom"
           This exposes a previously private API that allows you to pass a "virDomainPtr" object
           directly from libvirt to libguestfs.

       "guestfs_blockdev_setra"
           Adjust readahead parameter for devices.  See "blockdev --setra" command.

       "guestfs_btrfs_balance"
       "guestfs_btrfs_balance_cancel"
       "guestfs_btrfs_balance_pause"
       "guestfs_btrfs_balance_resume"
       "guestfs_btrfs_balance_status"
           Balance support for Btrfs filesystems (Hu Tao).

       "guestfs_btrfs_filesystem_defragment"
           Filesystem defragmentation support for Btrfs filesystems (Hu Tao).

       "guestfs_btrfs_image"
           Create an image of a Btrfs filesystem (Chen Hanxiao)

       "guestfs_btrfs_qgroup_assign"
       "guestfs_btrfs_qgroup_create"
       "guestfs_btrfs_qgroup_destroy"
       "guestfs_btrfs_qgroup_limit"
       "guestfs_btrfs_qgroup_remove"
       "guestfs_btrfs_qgroup_show"
       "guestfs_btrfs_quota_enable"
       "guestfs_btrfs_quota_rescan"
           Quote support for Btrfs filesystems (Hu Tao).

       "guestfs_btrfs_rescue_chunk_recover"
           Scan and recover the chunk tree in Btrfs filesystems (Hu Tao).

       "guestfs_btrfs_rescue_super_recover"
           Restore superblocks in Btrfs filesystems (Hu Tao).

       "guestfs_btrfs_replace"
           Replace a device in a Btrfs filesystem (Cao Jin).

       "guestfs_btrfs_scrub"
       "guestfs_btrfs_scrub_cancel"
       "guestfs_btrfs_scrub_resume"
       "guestfs_btrfs_scrub_status"
           Scrub a Btrfs filesystem (Hu Tao).

       "guestfs_btrfs_subvolume_get_default"
           Get the default subvolume of a Btrfs filesystem (Hu Tao).

       "guestfs_btrfs_subvolume_show"
           List detailed information about the subvolume of a Btrfs filesystem (Hu Tao).

       "guestfs_btrfstune_enable_extended_inode_refs"
       "guestfs_btrfstune_enable_skinny_metadata_extent_refs"
       "guestfs_btrfstune_seeding"
           Various tuning parameters for Btrfs filesystems (Chen Hanxiao).

       "guestfs_c_pointer"
           Return the C pointer to the underlying "guestfs_h *".  This allows interworking of
           libguestfs bindings with bindings from other libraries.  For further information see
           https://bugzilla.redhat.com/1075164

       "guestfs_copy_in"
       "guestfs_copy_out"
           Flexible APIs for recursively copying directories of files between the host and guest
           filesystem.  Previously these were available only as guestfish commands, but now any
           API users can call them (Pino Toscano).

       "guestfs_part_get_gpt_guid"
       "guestfs_part_set_gpt_guid"
           Get and set the GPT per-partition GUID.

       "guestfs_part_get_mbr_part_type"
           Get MBR partition type (Chen Hanxiao).

       "guestfs_set_uuid_random"
           Set the UUID of a filesystem to a randomly generated value; supported filesystems
           currently are ext2/3/4, XFS, Btrfs, and swap partitions.  (Chen Hanxiao).

       Other API changes

       "guestfs_disk_create" can now use VMDK files as backing files.

       "guestfs_btrfs_subvolume_snapshot" takes extra optional parameters (all added by Hu Tao):

       "ro"
           for creating a read-only Btrfs snapshot

       "qgroupid"
           for adding the snapshot to a qgroup

       "guestfs_btrfs_subvolume_create" can also take the optional "qgroupid" parameter (Hu Tao).

       "guestfs_set_uuid" can set UUID of swap partitions, Btrfs (Hu Tao, Chen Hanxiao).

       "guestfs_copy_device_to_file" and "guestfs_copy_file_to_file" have a new optional "append"
       parameter, allowing you to append to the output file instead of truncating it.

       "guestfs_mkfs" has a new optional "label" parameter to set the initial label of the new
       filesystem (Pino Toscano).

       "guestfs_set_label" and "guestfs_set_uuid" now set "ENOTSUP" as errno when there is no
       implemented support for the filesystem of the specified mountable (Chen Hanxiao).

       Environment variables now let you write "LIBGUESTFS_DEBUG=true", "LIBGUESTFS_DEBUG=0" and
       so on.

       All "guestfs_sfdisk*" APIs have been deprecated.  Because sfdisk(8) was rewritten,
       incompatibly, upstream, we don't recommend using these APIs in future code.  Use the
       "guestfs_part*" APIs as replacements.

       APIs such as "guestfs_download" do not truncate /dev/stdout or /dev/stderr when writing to
       them, meaning that if you redirect stdout or stderr to a file, the file is no longer
       truncated.

   Build changes
       The daemon no longer uses its own separate copy of gnulib.  Instead it shares a single
       copy with the library.

       OCaml .annot files are now created, so IDEs and editors like emacs and vi can browse OCaml
       types in the source code.

       Various fixes to allow different host/appliance architecture builds (Pino Toscano).

       Automake is now used directly to build all the OCaml programs, instead of ad hoc Makefile
       rules.  One side effect of this is to enable warnings in all the C code used by OCaml
       programs.

       "-fno-strict-overflow" is used throughout the build to avoid dubious GCC optimizations.

       Multiple cleanups to support GCC 5.

       OCaml OUnit2 is needed to run some OCaml tests.

       Creating a statically linked libguestfs.a should work again.

       The src/api-support subdirectory and its scripts are no longer used.  Instead we store in
       the generator/actions.ml when the API was added to libguestfs.

   Internationalization
       The translation service has changed from Transifex to Zanata.

       Many more translations are available now, for both library and tools messages and
       documentation.

   内部
       In all OCaml tools, there are now common "error", "warning", "info" functions, and common
       way to set and get the --quiet, -x (trace)  and -v (verbose) flags, and colour
       highlighting used consistently.

       "COMPILE_REGEXP" macros are used to simplify PCRE constructors and destructors.

       In the generator, "Pointer" arguments have finally been implemented.

       Internal identifiers no longer use double and triple underscores (eg.
       "guestfs___program_name").  These identifiers are invalid for C99 and C++ programs,
       although compilers would accept them.

       The daemon no longer parses "guestfs_*" options from /proc/cmdline.  Instead it only takes
       ordinary command line options.  The appliance init script turns /proc/cmdline into daemon
       command line options.

       The tests can now run the daemon as a "captive process", allowing it to be run directly on
       the host.  The main advantage of this is we can run valgrind directly on the daemon during
       testing.

RELEASE NOTES FOR LIBGUESTFS 1.28

       These release notes only cover the differences from the previous stable/dev branch split
       (1.26.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       Tools

       virt-v2v(1) and virt-p2v(1) are tools for converting from foreign hypervisors (such as
       VMware or Xen) or physical machines, to KVM.  These tools were previously a separate
       project.  The code for both tools has been integrated into the libguestfs tree.  As part
       of the refactoring, virt-p2v has been rewritten (from Ruby, now C), and virt-v2v now uses
       several modern features of qemu which make it run many times faster than before.
       virt-v2v(1) can import from: VMware vCenter, VMware OVA files, local disk files, libvirt,
       RHEL 5 Xen.  It can output to: oVirt or Red Hat Enterprise Virtualization (RHEV-M),
       OpenStack Glance, libvirt, qemu, local disk files.

       virt-log(1) is a new tool for listing log files from guests.  It supports a variety of
       guests including Linux traditional, Linux using journal, and Windows event log.

       virt-builder(1) has a new "--machine-readable" option to make it simpler to consume virt-
       builder from other programs.

       New virt-builder(1) and virt-customize(1) --chmod option.

       virt-sysprep(1) will now remove: systemd journals, anaconda logs, lightdm logs, debian-
       installer files, apt logs, exim logs, ConsoleKit logs, firewalld logs, grubby logs,
       proftpd logs, libvirt/libxml logs, and several other log files.  The virt-sysprep
       "user-account" operation is now able to remove or keep particular user accounts.  (Pino
       Toscano).

       New guestmount(1) --fd option, allowing you to run guestmount captive under another
       process.

       virt-sparsify(1) has a new --tmp option allowing you to precisely control where temporary
       files are stored.

       virt-sparsify(1) can now write to a block device.

       virt-customize(1) and virt-sysprep(1) now support adding firstboot scripts to Windows
       guests.

       virt-cat(1), virt-edit(1), virt-ls(1) now support the -m option, allowing you to override
       automatic inspection of guests and instead specify where to mount partitions (Pino
       Toscano).

       The virt tools now have coloured output: green for OK, red for errors, blue for warnings.

       Language bindings

       You can build a Python distribution using "make -C python sdist"

       Ruby bindings have switched from "Test::Unit" to "MiniTest".

       The Java bindings are now compatible with OpenJDK 8 (Pino Toscano).

       Inspection

       Oracle Linux is returned as "oraclelinux" (Nikos Skalkotos).

       Linux guests which do not have /etc/fstab can now be handled (Pino Toscano).

       Minix is returned as "minix" (Pino Toscano).

       Architectures

       Aarch64 (64 bit ARM) support has been added.

       Inspection and the "guestfs_file_architecture" call can now recognize arm (32 bit) and
       aarch64 guests.

   Security
       CVE-2014-0191 Network usage and entity resolution in XML parsing
           Libguestfs previously used unsafe libxml2 APIs for parsing libvirt XML.  These APIs
           defaulted to allowing network connections to be made when certain XML documents were
           presented.  Using a malformed XML document it was also possible to exhaust all CPU,
           memory or file descriptors on the machine.

           Since the libvirt XML comes from a trusted source (the libvirt daemon)  it is not
           thought that this could have been exploitable.

           This was fixed in libguestfs ≥ 1.27.9 and the fix was backported to stable versions ≥
           1.26.2, ≥ 1.24.9, ≥ 1.22.10 and ≥ 1.20.13.  (Thanks: Dan Berrange, Pino Toscano).

       Shellshock (bash CVE-2014-6271)
           This bash bug indirectly affects libguestfs.  For more information see:
           https://www.redhat.com/archives/libguestfs/2014-September/msg00252.html

   API
       New APIs

       "guestfs_clear_backend_setting"
       "guestfs_get_backend_setting"
       "guestfs_set_backend_setting"
           Use these APIs to set individual backend settings.

       "guestfs_cpio_out"
           Convert a directory within the disk image to cpio format.

       "guestfs_journal_get_realtime_usec"
           Fetch precise journal times, see sd_journal_get_realtime_usec(3).

       "guestfs_lstatns"
       "guestfs_lstatnslist"
       "guestfs_statns"
           Enhanced versions of "guestfs_lstat", "guestfs_lstatlist", "guestfs_stat" which return
           nanosecond timestamps.

   Build changes
       Libguestfs can now be built with qemu 2.x.

       Add support for packaging the appliance on Mageia (Joseph Wang, Thierry Vignaud).

       Augeas is now a required dependency.

       Flex and bison are now required dependencies.

   内部
       User-Mode Linux (UML) is no longer a supported backend (although still available).  It
       will be supported again once someone steps in and fixes various regressions and brokenness
       in the UML (Linux) kernel.

       You can now connect gdb to qemu by specifying "LIBGUESTFS_BACKEND_SETTINGS=gdb"

       Serial BIOS (sgabios) is now used by the libvirt backend (on x86 only)  so that we see
       early BIOS messages.

       For the OCaml virt tools, exceptions are now handled and printed by a common function.

       A GCC warning about large stack frames is now enabled by default.  Several places that
       used large arrays and structures on the stack have been fixed.

       There is now a test for booting the appliance repeatedly.  Useful for finding kernel
       leaks.  See: tests/qemu/qemu-boot.c

       There is a test for testing the speed of various qemu features such as virtio-serial
       uploads and block device writes.  See: tests/qemu/qemu-speed-test.c

       GCC warnings are now enabled for OCaml-C bindings in the OCaml virt tools.

       The code for editing files used by virt-edit(1), guestfish(1) "edit" command,
       virt-customize(1) --edit option and more is now shared between all these utilities (thanks
       Pino Toscano).

       The FUSE tests were rewritten in C to ensure finer control over how system calls are
       tested.

       The update-bugs.sh script has been fixed so it should no longer create an empty "BUGS"
       file if the Bugzilla server is unavailable.

       The virt-resize(1) tests now use a stochastic method to ensure much deeper and broader
       testing.

       When the network is enabled, the appliance now uses DHCP to acquire an IP address.

       If libvirt is being used then the appliance will connect to "virbr0" (can be overridden by
       setting "LIBGUESTFS_BACKEND_SETTINGS=network_bridge=<some_bridge>").  This enables full-
       featured network connections, with working ICMP, ping and so on.

RELEASE NOTES FOR LIBGUESTFS 1.26

       These release notes only cover the differences from the previous stable/dev branch split
       (1.24.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       Tools

       virt-customize(1) is a new tool for customizing virtual machine disk images.  It lets you
       install packages, edit configuration files, run scripts, set passwords and so on.
       virt-builder(1) and virt-sysprep(1) use virt-customize, and command line options across
       all these tools are now identical.

       virt-diff(1) is a new tool for showing the differences between the filesystems of two
       virtual machines.  It is mainly useful when showing what files have been changed between
       snapshots.

       virt-builder(1) has been greatly enhanced.  There are many more ways to customize the
       virtual machine.  It can pull templates from multiple repositories.  A parallelized
       internal xzcat implementation speeds up template decompression.  Virt-builder uses an
       optimizing planner to choose the fastest way to build the VM.  It is now easier to use
       virt-builder from other programs.  Internationalization support has been added to
       metadata.  More efficient SELinux relabelling of files.  Can build guests for multiple
       architectures.  Error messages have been improved.  (Pino Toscano)

       virt-sparsify(1) has a new --in-place option.  This sparsifies an image in place (without
       copying it) and is also much faster.  (Lots of help provided by Paolo Bonzini)

       virt-sysprep(1) can delete and scrub files under user control.  You can lock user accounts
       or set random passwords on accounts.  Can remove more log files.  Can unsubscribe a guest
       from Red Hat Subscription Manager.  New flexible way to enable and disable operations.
       (Wanlong Gao, Pino Toscano)

       virt-win-reg(1) allows you to use URIs to specify remote disk images.

       virt-format(1) can now pass the extra space that it recovers back to the host.

       guestfish(1) has additional environment variables to give fine control over the "><fs>"
       prompt.  Guestfish reads its (rarely used) configuration file in a different order now so
       that local settings override global settings.  (Pino Toscano)

       virt-make-fs(1) was rewritten in C, but is unchanged in terms of functionality and command
       line usage.

       Language bindings

       The OCaml bindings have a new "Guestfs.Errno" module, used to check the error number
       returned by "Guestfs.last_errno".

       PHP tests now work.  (Pino Toscano)

       Inspection

       Inspection can recognize Debian live images.

       Architectures

       ARMv7 (32 bit) now supports KVM acceleration.

       Aarch64 (ARM 64 bit) is supported, but the appliance part does not work yet.

       PPC64 support has been fixed and enhanced.

   Security
       Denial of service when inspecting disk images with corrupt btrfs volumes
           It was possible to crash libguestfs (and programs that use libguestfs as a library) by
           presenting a disk image containing a corrupt btrfs volume.

           This was caused by a NULL pointer dereference causing a denial of service, and is not
           thought to be exploitable any further.

           See commit d70ceb4cbea165c960710576efac5a5716055486 for the fix.  This fix is included
           in libguestfs stable branches ≥ 1.26.0, ≥ 1.24.6 and ≥ 1.22.8, and also in RHEL ≥ 7.0.
           Earlier versions of libguestfs are not vulnerable.

       Better generation of random root passwords and random seeds
           When generating random root passwords and random seeds, two bugs were fixed which are
           possibly security related.  Firstly we no longer read excessive bytes from
           /dev/urandom (most of which were just thrown away).  Secondly we changed the code to
           avoid modulo bias.  These issues were not thought to be exploitable.  (Both changes
           suggested by Edwin Török)

   API
       GUID parameters are now validated when they are passed to API calls, whereas previously
       you could have passed any string.  (Pino Toscano)

       New APIs

       "guestfs_add_drive_opts": new "discard" parameter
           The new "discard" parameter allows fine-grained control over discard/trim support for
           a particular disk.  This allows the host file to become more sparse (or thin-
           provisioned) when you delete files or issue the "guestfs_fstrim" API call.

       "guestfs_add_domain": new parameters: "cachemode", "discard"
           These parameters are passed through when adding the domain's disks.

       "guestfs_blkdiscard"
           Discard all blocks on a guestfs device.  Combined with the "discard" parameter above,
           this makes the host file sparse.

       "guestfs_blkdiscardzeroes"
           Test if discarded blocks read back as zeroes.

       "guestfs_compare_*"
       "guestfs_copy_*"
           For each struct returned through the API, libguestfs now generates "guestfs_compare_*"
           and "guestfs_copy_*" functions to allow you to compare and copy structs.

       "guestfs_copy_attributes"
           Copy attributes (like permissions, xattrs, ownership) from one file to another.  (Pino
           Toscano)

       "guestfs_disk_create"
           A flexible API for creating empty disk images from scratch.  This avoids the need to
           call out to external programs like qemu-img(1).

       "guestfs_get_backend_settings"
       "guestfs_set_backend_settings"
           Per-backend settings (can also be set via the environment variable
           "LIBGUESTFS_BACKEND_SETTINGS").  The main use for this is forcing TCG mode in the
           qemu-based backends, for example:

            export LIBGUESTFS_BACKEND=direct
            export LIBGUESTFS_BACKEND_SETTINGS=force_tcg

       "guestfs_part_get_name"
           Get the label or name of a partition (for GPT disk images).

   Build changes
       The following extra packages are required to build libguestfs 1.26:

       supermin ≥ 5
           Supermin version 5 is required to build this version of libguestfs.

       flex, bison
           Virt-builder now uses a real parser to parse its metadata file, so these tools are
           required.

       xz  This is now a required build dependency, where previously it was (in theory) optional.

   内部
       PO message extraction rewritten to be more robust.  (Pino Toscano)

       "podwrapper" gives an error if the --insert or --verbatim argument pattern is not found.

       Libguestfs now passes the qemu -enable-fips option to enable FIPS, if qemu supports it.

       "./configure --without-qemu" can be used if you don't want to specify a default
       hypervisor.

       Copy-on-write [COW] overlays, used for example for read-only drives, are now created
       through an internal backend API (".create_cow_overlay").

       Libvirt backend uses some funky C macros to generate XML.  These are simpler and safer.

       The ChangeLog file format has changed.  It is now just the same as "git log", instead of
       using a custom format.

       Appliance start-up has changed:

       ·   The libguestfs appliance now initializes LVM the same way as it is done on physical
           machines.

       ·   The libguestfs appliance does not write an empty string to /proc/sys/kernel/hotplug
           when starting up.

           Note that you must configure your kernel to have "CONFIG_UEVENT_HELPER_PATH="""
           otherwise you will get strange LVM errors (this applies as much to any Linux machine,
           not just libguestfs).  (Peter Rajnoha)

       Libguestfs can now be built on arches that have ocamlc(1) but not ocamlopt(1).  (Hilko
       Bengen, Olaf Hering)

       You cannot use "./configure --disable-daemon --enable-appliance".  It made no sense
       anyway.  Now it is expressly forbidden by the configure script.

       The packagelist file uses "m4" for macro expansion instead of "cpp".

RELEASE NOTES FOR LIBGUESTFS 1.24

       These release notes only cover the differences from the previous stable/dev branch split
       (1.22.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       User-Mode Linux (UML) can be used as an alternative backend (ie. instead of KVM).  This
       improves performance especially when using libguestfs inside a VM (eg. in the cloud).  UML
       is supported as a first-class backend.  See "USER-MODE LINUX BACKEND" in guestfs(3) for
       how to use this.

       ARM (32 bit) and PPC64 are now fully supported.

       Tools

       virt-builder(1) is a new tool for building virtual machine images.  It lets you rapidly
       and securely create guests and customize them.

       New virt-sysprep(1) operations: Remove files in /tmp and /var/tmp.  Remove RPM database
       files.  Change root and user passwords.  More log files are removed.  New operations which
       are not enabled by default: Create random UUIDs for filesystems.  Reset firewall rules.
       (Wanlong Gao)

       virt-resize(1) and virt-sysprep can now use URIs to specify a remote disk.

       Use "guestfish -N filename=type" to create a named disk image (instead of the default
       test1.img etc).

       virt-sparsify(1) now tests if there is enough disk space to complete the operation,
       instead of possibly running out of space half way through.

       virt-format(1) and virt-make-fs(1): new --label option for setting filesystem label.

       virt-resize --no-sparse flag can be used to resize on to partitions and other targets that
       are not zeroed.

       Language bindings

       New bindings for the Go programming language.

       API

       Support for the systemd journal.

       "guestfs_add_drive_opts" can now control the qemu caching mode through a new "cachemode"
       parameter.  You can select improved performance for temporary drives, or safety.

       "guestfs_set_label" now works for XFS and btrfs.

       New GUESTFS_EVENT_WARNING event for warning messages.

       Inspection

       Better inspection of SUSE guests (Olaf Hering).

       Better support for non-standard Windows %systemroot% (Matthew Booth).

       Enhanced error reporting for Augeas errors.

   Security
       CVE-2013-2124
           https://bugzilla.redhat.com/show_bug.cgi?id=968306

           A denial of service was possible when inspecting certain guests.  The fix has been
           backported to 1.20 and 1.22 branches.

       CVE-2013-4419
           https://www.redhat.com/archives/libguestfs/2013-October/msg00031.html

           Fix insecure temporary directory handling for remote guestfish.  The fix has been
           backported to 1.20 and 1.22 branches.

   New APIs
        add-drive-scratch: Add a temporary scratch drive
        aug-label
        aug-setm
        journal-open: Systemd journal support
        journal-close
        journal-next
        journal-skip
        journal-get
        journal-get-data-threshold
        journal-set-data-threshold
        remount: Allow rw flag to be adjusted on mounted filesystems
        set-uuid: Set UUID of filesystem

       "is-file", "is-dir", "is-blockdev", "is-chardev", "is-fifo", "is-socket" APIs now have an
       extra "followsymlinks" flag.

       "add-drive" has a new "cachemode" parameter.

   Build changes
       The following packages are required to build libguestfs 1.24:

       Augeas ≥ 1.0.0

       The following optional packages may be added to enhance functionality but are not
       required:

       sd-journal
           To read journal files from guests which use that.

       url_mkcow
           For UML backend.

       curl
       gpg
       xz  For virt-builder.

       golang ≥ 1.1.1
           For Go language bindings.

   内部
       New "make check-*" rules replace "make extra-tests".  See "make help" and guestfs(3) for
       details.

       Perl code can now be valgrinded.

       Inspection code is now fuzz-tested.

       "make" no longer recurses into the generator directory in every other directory.  This
       reduces the overhead of builds considerably.

       Additional tests for Augeas, hivex.

       Add a launch timeout of 20 minutes waiting for the appliance to start up.

       Add a timeout (4 hours) to all tests so we can catch the case where qemu or other
       components hang.

       Use kvmclock and "-cpu host".  This improves clock stability and overall performance.

       "./configure --enable-packet-dump" mode is fixed.

       "./configure --enable-valgrind-daemon" mode has been rewritten.  It is now feasible for
       developers to keep this flag enabled at all times.

       Backends have been refactored to be modular (although they are not actually loadable
       modules).

       When enabled, the network now uses resolver configuration (ie. /etc/resolv.conf) from the
       host.

RELEASE NOTES FOR LIBGUESTFS 1.22

       These release notes only cover the differences from the previous stable/dev branch split
       (1.20.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       API

       Remote access to disks:

       ·   Network Block Device (nbd)

       ·   Secure Shell (ssh)

       ·   HTTP and HTTPS

       ·   FTP and FTPS

       ·   iSCSI

       ·   Gluster

       ·   Ceph/rbd (Mike Kelly)

       ·   Sheepdog

       ·   TFTP

       The SYSLINUX and EXTLINUX bootloaders can now be installed in disk images using the API.

       Inspection can now handle filesystems such as btrfs where subvolumes are separately
       mountable (Matthew Booth).

       "Attach methods" are now known as "backends".  Compatibility with existing code is
       preserved.

       Filenames can contain ':', as long as newer QEMU is being used.

       Tools

       Virt-alignment-scan and virt-df scan multiple guests in parallel.

       Guestmount now passes errno accurately back to userspace in almost all cases.

       Guestfish and other tools can now use a URI-like syntax to access remote disks, eg:

        guestfish -a ssh://example.com/path/to/disk.img

       Guestfish and guestmount now allow you to specify the filesystem type when mounting, which
       is more secure (Dave Vasilevsky).

       Guestfish is now the "guest filesystem shell".

       Guestfish allows only 1 "true" "t" "yes" "y" "on" 0 "false" "f" "no" "n" "off" for boolean
       values (case insensitive), and gives an error for all other strings.

       New tool "guestunmount" for unmounting FUSE filesystems safely.

       "guestmount --no-fork" flag prevents guestmount from daemonizing.

       Virt-resize now uses sparse copies by default, saving considerable space for guests which
       are mostly empty.

       Bash tab completion has been rewritten and can now handle most tools, and correctly tab-
       complete "--long" options.  In addition, bash completion scripts are loaded on demand.

       Language bindings

       The Java API now supports events.

       The Python object now inherits from the "object" base class.

       Python methods which previously returned lists of tuples can now be made to return a
       Python dict.  For backwards compatibility, you have to enable this by using the
       constructor option "guestfs.GuestFS (python_return_dict=True)".

       The PHP bindings are now tested properly, and have had multiple fixes.

       The long-deprecated Perl "Sys::Guestfs::Lib" library has been removed.
       https://www.redhat.com/archives/libguestfs/2013-April/msg00001.html

       

       新しいプログラム例は、デバッグを有効化し、ログメッセージを採取する方法を示します。

       Other

       Distributors can add arbitrary extra packages to the appliance by doing:

        ./configure --with-extra-packages="list of package names"

       Distributors can use:

        ./configure --with-supermin-extra-options="..."

       to add arbitrary extra options to supermin.

   Security
       No security issues were found in this release.

        extlinux
        feature-available

        part-set-gpt-type
        rename
        set-program
        syslinux

       C のみ:

        guestfs_event_to_string

   内部
       The febootstrap tool has now been renamed to "supermin".  Libguestfs can use either, but
       now prefers "supermin".  http://people.redhat.com/~rjones/supermin/

       libxml2 が libguestfs をビルドするために必要です。

       (hivex の) hivexregedit プログラムが git からビルドするために必要です。

       Internal functions can no longer be used unless the caller defines "-DGUESTFS_PRIVATE=1".

       Enable C compiler warnings in Python, Ruby bindings.

       Fail early and clearly if libvirt does not support qemu/KVM (eg. if default libvirt
       connection is to Xen).

       "make print-subdirs" rule, useful for selectively running tests.

       Multiple fixes to allow separated (sourcedir != builddir) builds.

       Multiple fixes to Haskell bindings.

       "ln" and "ln-f" APIs now capture "errno" correctly.

       Language binding tests use (mostly) a standard numbering scheme and aim to test the same
       range of features in each language.  Also the number of launches required has been reduced
       so these tests should run much more quickly.

       Library code internally uses GCC "__attribute__((cleanup))" (if available) to simplify
       memory allocation.

       Internal header files have been reorganized.  See the comments in src/guestfs-internal*.h

       Internal code shared between the library and certain tools is now located in a static
       "libutils" library.

       Almost all subdirectories can now use parallel builds, although note that the top-level
       directories still build in series.

       Use of "PATH_MAX" and "NAME_MAX" has been eliminated from the code.

       The Java API now requires JVM ≥ 1.6.

       Force use of "serial-tests" with automake ≥ 1.12.

       Use of sockets in the library protocol layer is abstracted, allowing other non-POSIX
       layers to be added in future (see src/conn-socket.c).

       "qemu-img info --output json" is used if available, for more secure parsing of the output
       of this command.

       Distros can now use "make INSTALLDIRS=vendor install" to place Ruby bindings in vendordir.
       This eliminates a non-upstream patch carried by both Fedora and Debian.

       Valgrind log files are now written to tmp/valgrind-DATE-PID.log

       "make clean" cleans the local "tmp/" directory.

       The C API tests have been rewritten using a more flexible generator language that allows
       arbitrary C code to be executing during tests.

libguestfs 1.20 のリリースノート

       These release notes only cover the differences from the previous stable/dev branch split
       (1.18.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
       libvirt and sVirt (SELinux confinement)

       You can optionally use libvirt to launch and manage the backend appliance by:

       ·   setting "LIBGUESTFS_ATTACH_METHOD=libvirt[:URI]"

       ·   using "./configure --with-default-attach-method=libvirt[:URI]"

       ·   or calling the API method "guestfs_set_attach_method"

       SVirt (SELinux confinement) is used to secure the libguestfs appliance, if the libvirt
       backend is selected.

       virtio-scsi, larger number of drives, hotplugging

       Virtio-scsi is now used by default, if it is available.  This greatly increases the number
       of drives that can be added to a single libguestfs handle (up to 255).

       You can now hotplug drives (add and remove drives after launch).

       Libguestfs can now handle > 25 disks, in all APIs, tools and tests.

       You can label drives when adding them, then refer to them by label
       (/dev/disk/guestfs/LABEL) instead of having to use device names (/dev/sda).

       new library features

       POSIX Access Control Lists (ACLs) and Linux filesystem capabilities can now be read and
       written through the API.

       Windows Dynamic Disks are now supported.  The metadata can only be read (volumes cannot be
       modified or created).  However the data/filesystems in the volumes themselves can be
       mounted, read and written (Matthew Booth).

       Hivex (Windows Registry editing) is now directly supported through the API, making reading
       or editing the Windows Registry much more efficient.

       Several libguestfs APIs were reimplemented so they no longer have any limits on output.
       The reimplemented APIs are: "guestfs_cat", "guestfs_find", "guestfs_read_file",
       "guestfs_read_lines", "guestfs_write", "guestfs_write_append", "guestfs_lstatlist",
       "guestfs_lxattrlist", "guestfs_readlinklist", "guestfs_ls".

       virt tools

       "guestfish touch 'win:c:\new_file'" now works as expected.

       "guestfish" has a new --network option, which enables the user network in libguestfs.

       You can set "GUESTFISH_PS1" to use fancy prompts in "guestfish".

       "rsync", "ssh", "less" and "lrzip" commands are now available in virt-rescue.  In
       addition, "rsync" can be used through the API for doing incremental copies.

       "virt-sparsify" uses qcow2 v3 for increased efficiency.

       "virt-sysprep" enhancements:

       ·   generate new UUIDs for PVs and VGs

       ·   remove the local machine ID (Wanlong Gao)

       ·   remove ABRT data (Wanlong Gao)

       ·   remove puppet keys and log files (Wanlong Gao)

       ·   remove process accounting files (Wanlong Gao)

       ·   new --firstboot parameter allowing firstboot scripts for customizing guests

       ·   remove HOSTNAME field from "ifcfg-eth*" files (Wanlong Gao)

       ·   miscellaneous improvements for SuSE (Olaf Hering)

       ·   remove man pages cache (Wanlong Gao)

       ·   remove crash data generated by kexec-tools (Wanlong Gao)

       "virt-make-fs" can now create virtual floppy disks (VFDs).

       "guestmount" has a --pid-file option, which can be used to avoid a race condition between
       unmounting the filesystem and using the underlying disk image.

       language bindings

       Full-featured Lua bindings have been added in this release (thanks to Jerome Vuarand for
       many suggestions).

       In Ruby, optional arguments hash is optional.

       In Python, optional arguments now don't use special "sentinel" values, so any integer can
       be passed as an optional argument.

       Erlang bindings now come with examples and tests.

       Erlang bindings now handle 64 bit integer parameters correctly.

       The automated 'bindtests' now test for 64 bit cleanliness in parameter passing.  Several
       bugs in the bindings were found and fixed as a result.

       Better handling of blocking and non-blocking functions should make libguestfs calls more
       efficient.

       inspection

       Windows guests with unlimited-sized Registries are now supported.  By adding the hivex API
       to the libguestfs API, it is much more efficient and easier to inspect and modify the
       Windows Registry in guests.

       Better support for SuSE guests (Olaf Hering).

       Return the architecture of installed applications (John Eckersberg).

       Windows 8 is now supported.

       Fedora 18 is now supported.

       Inspection of ISOs/CDs/DVDs can now use the libosinfo database.

       ports

       Libguestfs without the appliance can be compiled on Mac OS X (Masami HIRATA).

       RHEL 5 is now explicitly supported through the 'oldlinux' branch in upstream git.

       PowerPC 64 bit is now supported.  Also libguestfs has been examined for endianness bugs
       and these have been fixed.

       daemon

       A man page for the daemon (guestfsd(8)) is included.

   Security
       guestfish history file

       The $HOME/.guestfish history file is now created with 0600 permissions (instead of 0644
       before) so it is no longer world readable.

       CVE-2012-2690

       Old versions of both "virt-edit" and the "guestfish" "edit" command created a new file
       containing the changes but did not set the permissions, etc of the new file to match the
       old one.  The result of this was that if you edited a security sensitive file such as
       /etc/shadow then it would be left world-readable after the edit.

       この問題は CVE-2012-2690 に割り当てられおり、libguestfs ≥ 1.16 において修正されています。

       In the C API only:

        guestfs_push_error_handler
        guestfs_pop_error_handler

   内部
       qemu ≥ 1.1 is required (≥ 1.2 preferred).

       febootstrap ≥ 3.20 is required.

       libvirt is optional, but if you want to use the new libvirt backend for launching the
       appliance then libvirt ≥ 0.10.2 would be required.

       Coverity has been run over the complete codebase, and many issues fixed (thanks Ondrej
       Vasik, Kamil Dudka).

       Functions which previously had no optargs can now be converted to ones with optargs,
       making extending the API much more flexible.  Source and binary backwards compatibility is
       preserved for users of the API.

       The way that libguestfs APIs and structures are represented in the generator has changed
       to use an OCaml struct instead of a tuple.  This makes generator descriptions more
       flexible and easier to understand.  For details see commits 39d1a7db and eb185eef.

       Separation of the library code into more files:

       ·   Launch backends are now located in separate files eg. src/launch-appliance.c,
           "src/launch-libvirt.c".

       ·   Generated action code is now split over several src/action*.c files, for faster
           compilation.

       ·   The huge src/guestfs.c file is now split into smaller logical units.

       POD (documentation) is now generated using a rewritten Perl program instead of pod2* +
       shell scripts.

       Man pages now contain stable dates (Hilko Bengen).

       Skipped tests now exit with code 77, so they appear as "SKIP:" in "make check" output.

       The parallel mount-local test has been rewritten in C (RHBZ#838081).

       Ruby 1.8.5 is now supported (though Ruby ≥ 1.9 is preferred).

       Perl bindings can be disabled via "./configure --disable-perl" (Wulf C. Krueger).  Note
       that Perl is still required in order to build libguestfs.

       Java bindings are now enabled/disabled using "./configure --with-java" or "./configure
       --without-java" (Wulf C. Krueger).

       New configure options "./configure --enable-code-profiling" and "./configure
       --enable-code-coverage".

       Multiple fixes to use of 64 bit integers in language bindings.

       The appliance backend now uses sgabios instead of vgabios (Dan Berrange).

       The "./run" script now sets enough environment variables that you can run OCaml, Python,
       Ruby, Java, GJS, Erlang, Lua programs.

       "./run --test" flag for running tests with minimal output.  It also prints the time taken
       to run each test.

       The "./run" script now builds up paths cumulatively, meaning that you can use "./run"
       twice, or use the libguestfs and libvirt "./run" scripts together.

       You can extract a list of external commands required by the daemon, making building the
       appliance on certain distros easier (Olaf Hering).

       The "virt-rescue" command is now tested during "make check".

       The generator now removes unused generated files.  This helps when going back and forth
       with git rebase, git bisect, etc.

       Tests now run in a separate toplevel "tmp/" directory in the source.  This allows the
       directory to be labelled for SELinux (sVirt), and also makes it easier to clean up.

       "make syntax-check" now works to a greater extent, and many problems in the main code that
       were found by syntax-check have been fixed (thanks Jim Meyering).

       Emacs mode (-*- foo -*-) has been added to generated files.

       Progress bar output is now sent to /dev/tty so it doesn't end up in the regular output of
       the program.  virt-resize and virt-sparsify now suppress progress bars if stdout is not a
       tty.

       There is now a "./configure --without-libvirt" option.  This is useful for testing that
       the code still compiles without libvirt.

       There is now an internal mini-library for running commands.  This allows us to redirect
       errors from external commands into events.

       Code for handling temporary directories and the appliance cache was completely overhauled.

       Code for temporarily ignoring/disabling errors now looks like this:

        guestfs_push_error_handler (g, NULL, NULL);
        guestfs_mkdir (g, "/foo"); /* We don't care if this fails. */
        guestfs_pop_error_handler (g);

       The "tests/extra" directory has gone.  The "extra tests" are now split into separately
       runnable targets, such as "make check-valgrind".  Use "make help" to get a summary of the
       targets.

       The "lpj" option is passed to the appliance kernel when using TCG.  This should improve
       clock stability (thanks Marcelo Tosatti, Olaf Hering).

   内部
         Git hosting has moved to http://github.com/libguestfs

         The various test directories have been rearranged logically, and now
         all appear under 'tests/'.

         There is a 'make extra-tests' rule which runs ordinary tests and
         additional tests, using valgrind to check for memory problems.

         Multiple memory leaks and other problems found by valgrind and fixed.

         Support for optional arguments in the generator has been rewritten
         to provide more features and safety (Matthew Booth).

RELEASE NOTES FOR LIBGUESTFS 1.14

       These release notes only cover the differences from the previous stable/dev branch split
       (1.12.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
         Erlang bindings.

         virt-alignment-scan is a new tool to check the alignment of
         partitions within virtual machines or disk images.

         virt-sparsify is a new tool to make virtual machine disk images
         sparse.

         virt-sysprep is a new tool to make cloning guests from a template
         simpler.

       guestfish

          - New commands setenv, unsetenv, to set environment variables.

          - The input file and line number is printed in error messages.

          - guestfish progress bars are now a "mini-library" used by other
            tools too.

       guestmount

          - the --live option (for access to live VMs) now works.

       virt-cat

          - virt-cat can now handle Windows paths and drive letters (RHBZ#693359).

       virt-filesystems

          - the MBR partition type byte is displayed in --long output.

       virt-make-fs

          - virt-make-fs now sets the MBR partition type byte correctly,
            improving compatibility with Windows (RHBZ#746295).

       virt-resize

          - virt-resize can now work with guests using extended and logical
            partitions, in particular Ubuntu guests.

          - virt-resize can now align the first partition of Windows guests,
            improving performance.  The new virt-resize --align-first option
            controls this behaviour.

          - The virt-resize --machine-readable flag makes it possible to use
            virt-resize from other programs.

          - Partitions are now aligned to 128 sectors (usually 64K) by
            default.  This improves efficiency on high-end storage.  The new
            virt-resize --alignment option allows the alignment to be
            adjusted.

       virt-win-reg

          - The syntax for deleting registry keys and values is documented
            in the man page (RHBZ#737944).

          - GUESTFS_EVENT_ENTER is a new event type generated whenever a
            libguestfs function is called.

          - the library contains systemtap/DTrace probes.

          - the library can now be compiled without hivex (RHBZ#723474).

       inspection

          - Improve detection of Windows disks.

          - Adds support for:
                ttylinux - a minimal Linux
                Mageia (thanks Michael Scherer)
                OpenSUSE and zypper (thanks Michael Scherer, Vincent Untz)
                Ubuntu logos (thanks Michael Scherer)
                NetBSD and pkgsrc (thanks Michael Scherer)

          - Handle some guest types that use /dev/root in /etc/fstab.

          - Fix handling of guests with > 26 disks (thanks Matthew Booth)

   New APIs
         compress-out, compress-device-out, copy-device-to-device,
         copy-device-to-file, copy-file-to-device, copy-file-to-file,
         get-smp, part-to-partnum, set-smp.

         The mount API no longer implicitly adds -o sync,noatime options.

         add-domain has a new 'readonlydisk' optional parameter to control
         how <readonly/> disks are handled.

   内部
        - Coverity was run on the source and more bugs were identified and
          fixed.

        - PCRE library is now required to build libguestfs.

        - APIC is now the default for the appliance.  You can also enable
          SMP support in the appliance.

        - OCaml bindings now correctly acquire GC lock during callbacks.

        - Out of tree builds should now work correctly (thanks Hilko Bengen).

        - ./configure --with-extra="..." can be used by packagers to set
          the extra version string.

        - zero, zero-device APIs: if the blocks already contain zeroes,
          don't write zeroes, so that we don't unnecessarily make the
          underlying storage non-sparse.

        - is-zero, is-zero-device APIs: optimize these so zero detection is
          faster.

        - New event API allows more than one callback to be registered for
          each event, makes it possible to call the API from other languages,
          and allows nearly all log, debug and trace messages to be rerouted
          from stderr.

        - Greater FHS compliance for temporary files, including using /var/tmp
          for large cached files that should survive reboot (instead of /tmp).

        - guestfish, guestmount -m option allows mount options to be passed
          through to the underlying filesystem.

        - mkfs-opts allows filesystem features to be specified.

        - More intelligent handling of mountpoints, allowing mkmountpoint, mount
          and umount-all commands to work together properly.

        - Trace messages are prefixed with a distinct string, allowing them to
          be easily 'grepped' out from debug output.

        - guestfs_launch (guestfish 'run' command) now produces progress
          messages (a guestfish progress bar) if it takes longer than 5
          seconds to run.

        - Several long-running commands where we are unable to estimate time
          to completion generate "pulse mode" progress events.  Progress bar
          in guestfish has been updated to display these.

        - Publish new example code in: C, Perl, Python, OCaml, Ruby.

        - New virt-dhcp-address example program.

        - The Java and Ruby bindings have been improved greatly.

        - Perl includes a way to get the errno of the last error.

        - Python bindings now compatible with rpyc (thanks Erez Shinan).

        - Transifex is now being used to manage translations.
          http://www.transifex.net/projects/p/libguestfs/

        - Inspection now supports Red Hat Desktop, Slackware distributions.

        - Inspection no longer fails for Windows guests that have two or
          more disks.

        - Inspection can now tell the difference between Windows 2008 Server
          and Windows 7.

        - Inspection can detect 32 bit applications installed in 64 bit
          Windows, running on the WOW64 emulator.

        - A series of protocol fixes has fixed the old bug RHBZ#576879
          which used to cause errors during the upload command to lose
          protocol synchronization.

        - New logo!

   Security
         [none]

   New APIs
         first-private, get-attach-method, inspect-get-drive-mappings,
         inspect-get-product-variant,
         inspect-get-windows-current-control-set, next-private, resize2fs-M,
         set-attach-method.

   内部
        - The 'HACKING' file is obsolete.  The contents have been moved into
          a section of the guestfs(3) manual page.

        - libguestfs-test-tool simplified.  It no longer needs the static
          binary or tries to construct an ISO.

        - rpcgen-generated files are compiled with -fno-strict-aliasing
          which should be safer (thanks Matt Booth).

        - virt-resize was rewritten in OCaml.

        - guestfish and other tools tested with valgrind; some memory leaks
          were fixed.

          of the functionality of those tools.

        - guestfish, guestmount and the C tools use unified command line option
          parsing, so they support many common options such as '-a disk.img',
          '-d libvirt-domain', '-x', '-v'.  The old command line option
          parsing is preserved for compatibility in scripts etc.

        - guestfish no longer has any dependencies on Perl

          with a great deal of information about those applications.

        - Add support for inspecting: Linux Mint, Mandriva, FreeBSD.

        - guestfish --rw option (with no effect currently) to make potentially
          dangerous write access explicit.

          Eric Blake).

        - The first upstream version that introduced each API function is now
          documented in guestfs(3).

        - guestfs_last_errno allows you to retrieve the errno from the
          daemon, correctly translated to the local operating system.

        - Functions can now have optional parameters.

        - Progress bars and progress notifications can now happen for upload
          commands.

        - Appliance builder more careful about not leaving temporary files
          around in /tmp.

        - getfattr/setfattr commands added to virt-rescue.

        - ROADMAP file covers roadmap and goals for future releases.

   Security
        - New SECURITY section in guestfs(3) API documentation.

        - virt-inspector no longer runs any guest commands.

        - Inspection code is more careful about avoiding very large files
          from guests which might previously have caused a denial of service.

        - lgetxattr
        - mkfs-opts

   内部
        - C programs now only link precisely with the libraries that they use.

        - PCRE, libmagic, hivex and libvirt libraries are now completely
          optional for building.

        - Multiple memory leaks and file descriptor leaks fixed.

        - Add a POD wrapper to unify generation of man pages and HTML files
          across all programs.

        - Source includes phony images of Fedora, Debian, Ubuntu and
          Windows guests.

        - Ruby bindings have 'make install' rule.

        - <guestfs.h> is now a single file.

        - <guestfs.h> does not require XDR headers.

        - ocaml xml-light library is no longer required to build (thanks
          Maxim Koltsov).

        - ./configure --disable-[...] for each language binding (thanks
          Maxim Koltsov).

        - Old ocaml-viewer program removed (use guestfs-browser instead).

        - New C API test type 'InitScratchFS' makes the tests run a little
          more quickly.

        - Excluded packages in the appliance are now listed in a separate
          file appliance/excludelist.in, and can be customized per-distro.

RELEASE NOTES FOR LIBGUESTFS 1.6

       These release notes only cover the differences from the previous stable/dev branch split
       (1.4.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
        - Use a new method for creating and caching the appliance.  This
          greatly improves the performance of libguestfs, often by a factor
          of x 4 to x 5.

        - Support for guest inspection (like virt-inspector) via the ordinary
          API and all language bindings.  'guestfish -i' option is as a side-
          effect much quicker.

        - virt-inspector and core inspection API can now detect guests running:
          Fedora, Debian, Ubuntu, Windows, Red Hat Enterprise Linux, CentOS,
          Scientific Linux, Gentoo, Pardus, Arch Linux, MeeGo.

        - Support for LUKS whole-disk encryption in guests.

        - PHP バインディング。

        - Progress messages (and progress bars in guestfish and virt-resize)
          for certain long-running operations.

        - virt-df is now much more efficient.  Use '--one-per-guest' to restore
          the old per-guest isolation behaviour.

        - guestfish 'copy-in' and 'copy-out' commands for copying files and
          directories recursively in and out of the guest.

        - guestfish 'hexedit' command for doing binary edits to devices and
          files.

        - Change guestfish -i syntax to allow commands to be specified on the
          command line (retaining backwards compatibility).

        - guestfish '-d <domain>' for adding disks from libvirt domains.

        - guestfish '-N' option supports several new prepared disk image types:
                lvfs : disk with LV formatted with filesystem
                  lv : disk with LV
            bootroot : boot+root
          bootrootlv : boot and root on LV

        - guestfish 'more' and 'edit' commands now work with arbitrary files.

        - guestfish '--echo-keys' option allows you to echo keys/passphrases
          while typing them.

        - guestmount now supports -a / -d / -i options, like guestfish.

        - Use virtio-serial for communications with the appliance.  This
          also has a major performance benefit.

        - virt-edit '-b' option to create a backup of edited files.

        - virt-edit '-e' option for non-interactive edits to files.

        - Ability to capture core dumps from the appliance (thanks Matthew Booth).

        - virt-rescue now shuts down cleanly (thanks Matthew Booth).

        - virt-rescue now has a --network option to enable network access.

        - virt-resize can now handle guests which use GPT partition table format.

        - virt-resize has better support for shrinking guests.

        - virt-resize supports qcow2-format guests.

        - $TMPDIR can be used to override almost all temporary directory usage.

        - OCaml users can use an alternate OO-style of coding, eg. g#launch ()

        - The API supports calls which take optional parameters, eg.
            $g->add_drive_opts ("disk", readonly => 1);

        - Trace output now escapes and shortens large strings (thanks
          Matthew Booth).

        - Autosync is now on by default, resulting in more reliable behaviour
          when the handle is closed.

        - virt-df --uuid option allows you to follow a domain across migration
          and renaming.

        - Translations of manual pages.

   Security
        - CVE-2010-3851 libguestfs: missing disk format specifier when adding a disk
          https://www.redhat.com/archives/libguestfs/2010-October/msg00036.html
          This is comprehensively fixed in this release, and the fix will be
          backported to the other stable branches after more testing.

        - virt-inspector no longer relies on untrusted guest code to list
          applications in some guests.

          modifications.

        - Sort the domains into alphabetical order in virt-df.

        - Make mkfs-b command work for FAT and NTFS by mapping the blocksize
          parameter to the cluster size (RHBZ#599464).

        - Add version numbers to Perl modules (RHBZ#521674).

        - Localization now works for all the libguestfs tools (RHBZ#559963).
