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

=head1 RELEASE NOTES FOR LIBGUESTFS 1.4

These release notes only cover the differences from the previous stable/dev branch split (1.2.0).  For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball.

=head2 New features

 - guestfish lets you choose a prepared disk image, eg:
     guestfish -N fs:ext4

 - Add write support to guestmount (FUSE) module.

 - virt-resize can now resize the content of partitions and logical
   volumes in the guest, and we have better support for shrinking guests.

 - Bash tab-completion script for guestfish.

 - Add ZFS support to virt-rescue.

 - New tool 'virt-make-fs' for creating filesystems with content.

 - Allow suffixes on any guestfish number parameter, eg. "1M".

 - guestfish 'man' command opens the manual page.

 - guestfish supports a "heredoc" syntax for uploading files:
     upload -<<_end_ /foo
     content
     _end_

 - Some guestfish commands now print their output in octal or hex
   where appropriate (RHBZ#583242).

 - Allow dash prefix on guestfish command line.  This ignores any
   error from the second command:                   (RHBZ#578407)
     guestfish -- cmd1 : -cmd2 : cmd3

 - guestfish -h / help command now returns an error for non-existent
   commands (RHBZ#597145).

 - New 'supported' command in guestfish to list optional groups of
   commands which are supported by the daemon / configuration.

 - virt-inspector and guestfish -i now work for filenames which
   contain spaces (RHBZ#507810).

 - Change the protocol to use link-local addresses, to avoid
   conflicting with any address that the host might be using
   (RHBZ#588763).

 - libguestfs now sets the correct time and timezone on filesystem
   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).

 - Tools now support filesystem-on-image VMs (RHBZ#590167).

 - virt-list-partitions has a '-t' option to show the total size of disks.

 - Include extra Augeas lenses in the supermin appliance (Matthew Booth).

 - Add error and close callbacks.

 - Add explicit close method in the Perl API.

 - Multiple fixes for RHEL 5 compatibility.

 - Multiple fixes for Debian/Ubuntu compatibility.

 - Multiple revisions to improve the documentation.

=head2 Security

 - Fix a potential DoS in virt-inspector and virt-v2v if a specially
   crafted disk image contained a char device in place of one of the
   configuration files that we read under /etc (RHBZ#582484).
