Public bug reported:

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
