       guestfs-release-notes - libguestfs リリースノート

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).
