How do you envision migration working with NPIV?
Perhaps there could be inactive nodedevs (i.e. you would add define/undefine/start/stop verbs), and a <source name='...'> element would trigger creation/destruction of those nodedevs around the VM's lifetime. Then migration would trigger destruction on the source and creation on the destination. I haven't thought much about it though.
