@Rafi,
Thanks for the suggestion. What you describe used to happen to me when we were using Oneiric's libvirtd (LP#903212). Since upgrading to Precise I haven't experienced the exact problem you're having.
My issue is that libvirtd seems to temporarily stop responding, enough to block nova-compute, but it then responds to external commands later when I probe it.
Looking through my monitoring logs, I can see that libvirtd occasionally stops responding, but not for long enough to generate an alert. I speculate that this is a timing issue, where libvirtd has stopped responding for a very limited period and during that moment nova-compute attempts to poll libvirtd?
