libguestfs 1.4.0

Update: Fedora 13 users can try this package. Please up vote if it works for you.

I just released libguestfs 1.4.0. This is a new stable branch, starting with the previous development version. In the 1.4.x branch we’ll only add well-tested bug fixes.

The very extensive release notes for this version are attached below.


Release notes for libguestfs 1.4.0

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.

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.

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).

– part-get-bootable – get the bootable flag of a partition
– part-get-mbr-id – get the MBR type byte of a partition
– part-set-mbr-id – set the MBR type byte of a partition
– pvresize-size – resize a physical volume (with size)
– pwrite – write to part of a file
– resize2fs-size – resize an ext2/3/4 filesystem (with size)
– txz-in – unpack compressed tarball to directory (RHBZ#580556)
– txz-out – pack directory into compressed tarball (RHBZ#580556)
– vfs-label – get the filesystem label
– vfs-uuid – get the filesystem UUID
– vgscan – rescan for LVM physical volumes, volume groups and logical volumes
– write – create a new file
– zero-device – write zeroes to an entire device

Internals

– Extend the generator to support testing optional features.
– Stricter checks on input parameters to many calls (RHBZ#501893 RHBZ#501894)
– Extend the protocol to support sending arbitrary 8 bit data buffers.
– Ship 'BUGS' file with releases. This is a summary of the bugs in
the Red Hat Bugzilla database.
