> Anti-Affinity - When Vm deployment is done in parallel , anti-affinity rule is not honored.
> Steps to reproduce the problem:
> Setup:
> Advanced zone with 6 hosts.
> Create a new anti-affnity rule.
> Deploy 5 Vms in this anti-affnity rule.
> We see that some of the vms that belong to the same anti-affinity rules are getting deployed
on the same host.
