How would upgrades work? Presumably you'd have to get all the existing compute
nodes able to handle un-tunnelled live migrations, then you'd live-migrate from
the old compute nodes to the new ones using tunnelled migrations (where live
migration is possible), but after that everything would be un-tunnelled?
