You can set attributes on flavors that must match the attributes on hosts or the host aggregates. So you can basically always make sure a specific flavors goes to a specific compute node or type (like disks=ssd or class=gpu). Look at nova flavor extra_specs documentation and the aggregate_Instance_extra_specs under the scheduler options.

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