Comment 1 for bug 1377419

I tried recreating in single node and didn't encounter this. Vedu, could you comment on whether this occurs always on multi-node setup or happens inconsistently? If it occurs inconsistently would appreciate access to system to debug further. Also it seems that there was a problem in nova-compute with libvirt which leads to nova code to call vif unplug (but it won't do neutron port delete) so it should occur upstream too if there is a problem.
