you usually do that on an instance level with server groups. do you have an example where you might want to do it at the flavor level?

Thanks,
Kevin

Subject: [Openstack-operators] Setting affinity based on instance type

I'm sure this is possible but I'm trying to find the info I need in the docs so I figured I'd pitch this to you guys while I continue looking:

Is it possible to set an affinity/anti-affinity policy to ensure instance Type A is weighted for/against co-location on the same physical host with instance Type B?

Basically I have no requirement for server-group affinity but rather to ensure specific workloads are as separate as possible.

Thoughts?
