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.
