I have tested the patch on a KVM cluster at my emplyer and based on a
day or so of testing under heavy load, it fixes the bug for me.
The cluster consists of 7 machines each running up to 8 VM jobs in
parallel. Most are varous windows versions but some are Ubuntu Lucid.
Each job runs for arround
Verified in precise proposed using the breaklibvirt.sh from bug:961217.
breaklibvirt.sh completes 100 rounds of starting and stopping 4
instances without failures after updating to

To manage notifications about
Hello Adin, or anyone else affected,
Accepted libvirt into precise-proposed. The package will build now and
be available at
http://launchpad.net/ubuntu/+source/libvirt/0.9.8-2ubuntu17.5 in a few
hours, and then in the -proposed repository.
Please help us by testing this new package. See
** Description changed:
+ ==
+ SRU Justification
+ 1. Impact: when starting multiple VMs simultaneously, many may fail to start.
+ 2. Development fix: the attached patch was used upstream to fix the race
+ 3. Stable fix: use the same patch
+ 4. test case: start
Thanks, Adin - there is already a libvirt package in precise-proposed
awaiting verification. I will push this fix as soon as that package is
promoted to -updates.
** Also affects: libvirt (Ubuntu Precise)
Importance: Undecided

Thanks for reporting this bug, and especially for finding the patch
fixing the problem! I assume you are seeing this in 12.04 and not in
12.10? (Just making sure) If so I'll go ahead and mark this for SRU

Yep, this is 12.04.
This patch is included in libvirt 0.9.13, so I believe 12.10 is already
covered.
