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 2 minutes, before being killed and a fresh VM booted in it's place, so we have thousands of KVM invocations per day. Before we saw arround 5% of jobs would fail due to Libvirt errors. (mostly from get_domain_by_name from the perl bindings) This was reduced to 1.5% by making multiple retrys on the API call untill it worked. It now looks like the faliure rate is down to zero with the new version of libvirt.
