Doc Text:
Rebase package(s) to version: 1.1 Highlights, important fixes, or notable enhancements: @Errata Content Author: please include the following fixes in the rebase statement along with the features listed below in the release note (see comment 12 for details): - Persist tracking of fsfreeze state via filesystem, thus avoiding qemu-ga to forget fsfreeze state if it dies or is restarted - Allow guest-fsfreeze-thaw to run unconditionally, thus qemu-ga is still able to thaw the FS even if it dies or is restarted - Avoid blocking on atime update when reading /etc/mtab while the FS is frozen --- #Release Note: QEMU Guest Agent Updated The QEMU guest agent (qemu-guest-agent) has been updated to upstream version 1.1, which includes the following notable enhancements and bug fixes: The guest-suspend-disk and guest-suspend-ram commands can now be used to suspend to RAM or to disk on a Windows system. This update fixes a memory leak in the Windows communication code. The guest-network-get-interfaces command can now be used to acquire network interface information in Linux. This update provides file system freeze support improvements and fixes. This update includes various documentation fixes and small improvements.

Description Luiz Capitulino 2012-06-01 20:43:19 UTC 
The guest agent we have in RHEL6.3 was forked off from QEMU 1.0. The latest version of QEMU (v1.1) contains a more up to date guest agent. Let's update RHEL's qemu-ga to its latest upstream version.

test this bug as follow version:
# uname -r
2.6.32-331.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.323.el6.x86_64

guest:
# uname -r
2.6.32-279.el6.x86_64

qemu-guest-agent-0.12.1.2-2.327.el6.x86_64

steps:
1.boot guest with virtio serial 
....-chardev socket,path=/tmp/qga.sock,server,nowait,id=qga0 -device  virtio-serial -device virtserialport,chardev=qga0,name=org.qemu.guest_agent.0

2. Inside guest: #service qemu-ga start

3. On host: 
#nc -U /tmp/qga.sock

Comment 13 Martin Prpič 2012-11-21 13:39:24 UTC 
On second thought, the above bug fixes can probably be mentioned in the documentation shipped with RHBA-2012:13475. A note about this has been added to the Doc Text field along with the content present in the Release Notes.
