VM priority: By configuring these settings, the host clusters will be instructed to start or place high-priority VMs before medium- or low-priority VMs, ensuring that the high-priority VMs are allocated memory and other resources first (for better performance).

Preferred and possible owners of VMs: These settings influence the placement of VMs on the host cluster nodes. By default, there is no preferred owner, which means that the possible owners include all cluster nodes.

Availability sets: By placing VMs in an availability set (to improve continuity of service), VMM will attempt to keep these VMs on separate hosts whenever possible.
