Having a brain freeze day.
If I have no reservations set, and 5 VM's with 20GB RAM allocated each, I understand the 'minimum' points will be based on 5 x 10GB (50%).
What if these VM's are all highly active and using all their allocated RAM? Does the usage meter ignore that and still calculate based on the minimum 50% of allocation, or does it look and work out the actual active RAM being burned on the host at that time (again with no administrative reservation set)?
