I think it would be a good idea to summarize what has been brought up so far outside of this thread. To that effect, I've created an etherpad at https://etherpad.opendev.org/p/VFIOMigrationDiscussions and started filling it with some points. It would be great if others could fill in the blanks so that everyone has a chance to see what is on the table so far, so that we can hopefully discuss this on-list and come up with something that works.
