Random libvirt hangs


In the spirit of Jay's message, we have a long-running cluster (diablo/kvm) where about once every 3-4 weeks a user will complain that she cannot connect to a vm. Examining the compute node shows that libvirt-bin is hung. Sometimes restarting this process fixes the problem. Sometimes it does not, but rebooting the compute node and then the vm does. I just heard from people in my company operating another cluster (essex/kvm) that they have also seen this. I filed a bug about a month ago


Has any one been running a kvm cluster for a long time with real users and never seen this issue?
