If I set negative affinity on two VM that are currently on the same server, how long until
one of them migrates to a different host? Is the time configurable somewhere? I think that
as soon as I configure the negative affinity between the two VMs, they should begin to
migrate

Hi Maurice,
affinity is being handled during the scheduling process and not
afterwards. So already placed VMs will not move unless they will
be picked up by the load balancing process which obeys affinity rules.
The reason for it is to avoid adding noise on loaded setups.
However we should be able to make sure load balancing will handle
affinity as well and only then balance the cluster.
Do mind opening an RFE for it?
Thanks,
Doron
