<div>In case anyone else runs into this, one of our admins had changed the cluster to policy to optimize for speed rather than utilization. Reconfiguring this option resolved the issue and the migrations are no longer overloading a single host.</div>

<div>Is there any way migrate VM’s more evenly across the cluster when a host is being placed into maintenance? Currently it attempts to auto migrate all the VM’s to another single host and then balance out. When the destination host is more than 50% memory
utilized this has caused over subscription problems. Some of our more heavily used hosts ending up using all the memory and stop communicating with engine. If it’s not possible, how are other teams handling this? Manual migrations before maintenance mode?</div>
