Hi Michal,

Well right now all the vms running fine, and this vm hung issue happening occasionally. The following out put is one of my running VM

[root@kvm03 ~]# virsh qemu-monitor-command w7-DRAC '{"execute":"query-status"}'
{"return":{"status":"running","singlestep":false,"running":true},"id":"libvirt-17597"}

What state is qemu process in? You may try to "ping" qemu on the monitor:

virsh qemu-monitor-command $dom '{"execute":"query-status"}'

But this sounds like a qemu bug to me.
