Again begging for this to be pulled into stable-0.11 :-)

These exact patches were posted in time for the branch but got dropped
mainly because of confusion over whether all the concerns had been

It's a nice feature for a relatively small set of changes, and without
them libvirt can't do NIC hotplug
