[Openstack-operators] Live migration and VM anti-affinity

I can use nova  DifferentHostFilter to achieve VM anti-affinity, by passing in UUID of instance as scheduler hint.

I am thinking later if I need do live migration or VM Evacuation,  can anti-affinity relationship be still honored ?

If no, is there a way to make sure after live migration or VM evacuation, the original anti-affinity relationship can be kept ?
