So I had similar problem. In my case the problem was that during LM of multiple VMs network was overloaded and therefore QEMU/libvirt was unable to send/receive LM heartbeats. Solution was to tweak LM heartbeat configuration in libvirt/qemu.conf.
Tushar if you can still reproduce this issue can you upload libvirt/libvirtd.log somewhere? So I will be able to confirm that maybe we had the same problem and mark this bug as invalid if that's true.
