- Support for guest inspection (like virt-inspector) via the ordinary

Fedora, Debian, Ubuntu, Windows, Red Hat Enterprise Linux, CentOS,

Scientific Linux, Gentoo, Pardus, Arch Linux, MeeGo.

- virt-rescue now shuts down cleanly (thanks Matthew Booth).
|

|

- virt-rescue now has a --network option to enable network access.
|
||||
|

- virt-resize can now handle guests which use GPT partition table format.
|

|
||||
- virt-resize has better support for shrinking guests.
|
||||
|
||||
- virt-resize supports qcow2-format guests.
|
||||
|
||||
- $TMPDIR can be used to override almost all temporary directory usage.
|
||||
|
||||
- OCaml users can use an alternate OO-style of coding, eg. g#launch ()
|
||||
|
||||
- The API supports calls which take optional parameters, eg.
|

$g->add_drive_opts ("disk", readonly => 1);
|

|

- Trace output now escapes and shortens large strings (thanks
|

Matthew Booth).
|

|

- Autosync is now on by default, resulting in more reliable behaviour
|
||||
when the handle is closed.
|
||||
|

- virt-df --uuid option allows you to follow a domain across migration
|

and renaming.

Security
|
||||
|

- CVE-2010-3851 libguestfs: missing disk format specifier when adding a disk
|
||||
https://www.redhat.com/archives/libguestfs/2010-October/msg00036.html
|
||||
This is comprehensively fixed in this release, and the fix will be
|
||||
backported to the other stable branches after more testing.
|
||||
|
||||
- virt-inspector no longer relies on untrusted guest code to list
|
||||
applications in some guests.
