Title:
  Anti-Affinity causes instance provisioning to take a lot of time

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Hey there,

  we are facing massive issues regarding nova scheduling and octavia
  provisioning when talking about anti-affinity.

  It seems, that it is problematic that nova is scheduling instances in
  antiaffinity groups sometimes on the same host and reschedules them
  after reporting the host to the queue.

  It is at least even a problem in regards of normal instancescheduling,
  as it takes a lot more time to schedule a vm two or three times.

  Is there any solution for optimizing scheduling? Can nova be
  configured to check before second, third, whatever instance is
  created?

  I would appreciate an optimization in here as it is causing some
  trouble.

  Greetings

  Christian
