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).

library

   - non-printing characters are escaped correctly in debug output.
   - 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)
   - Add support for guests with HP Smart Array disks (thanks Matthew Booth)

febootstrap

   - FEBOOTSTRAP_KERNEL, FEBOOTSTRAP_MODULES environment variables can
     be set in order to choose which kernel to use for the appliance.

misc

   - ArchLinux support now working with Linux 3.0 (thanks Erik Nolte)
   - libvirt disks marked <readonly/> are now added readonly when
     using the virt-tools '-d' option.

Security¶

  (no security problems were found or fixed in this release)

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.
