Please note that this affects the rescue process as well. Same as above, the instance is stopped and the bridge removed. Nova tries to boot the new rescue instance and fails since it can't get the MTU for the (removed by linux bridge agent) bridge.
nova.compute.manager [instance: uuid] libvirtError: Cannot get interface MTU on 'brq800452d2-85': No such device
