[Bug 1394219] [NEW] Failed to deploy new instance that server group on failed host

 

Public bug reported:

when the host is down/disable, for deploying instance that belongs to
server group with affinity policy and other instances with same server
group on the down/disable host, the scheduling will fail. Because
scheduler is trying to find same host for the new instance.

This is also for after we honors the server group when evacuate, if the
instance is in server group with affinity can't be evacuated.
