Well also if you do live migration to host where an instance of same anti-affinity group member was live_migrated away within ~70sec, it will fail as anti-affinity filter still thinks there is an instance of the same group present. I have had a manual fix in the code for a couple of years to have updated information in AntiAffinity filter code straight from DB. What seems to work also is SIGHUP to nova-scheduler. So some parallel migration checking might not be enough if the information used is not up-to-date.
