Hmm, https://review.opendev.org/#/c/670591/ is new to devstack in Train 
and was backported to stable/stein. I wonder if that is too aggressive 
and is causing issues with operations where the guest is stopped and 
started, though for resize/migrate/shelve/unshelve the guest is 
destroyed on one host and re-spawned on another, so I would think that 
having a graceful shutdown for the guest wouldn't matter in those cases, 
unless it has to do with leaving the guest "dirty" somehow before 
transferring the root disk / creating a snapshot (in the case of 
shelve). Maybe we should bump that back up to 10 seconds?
