Hi Sean, Can you try to do virsh dumpxml and observe for any changes (i.e. MAC address, or slot/IDs, etc) - if the XML is identical (as it should be, besides the VNC IP/port) - then that sounds really weird.
Also, when you live migrate the VM to another host, then power off/on - does the problem happen then (during live migration, the XML stays identical, apart from the VNC IP/port)?
