VMware Resource Pools: Misplacement

A common issue is that VMs are placed outside of any resource pools, leaving them at the same level as the highest level of user-created resource pools.

The Limit and Reservation settings of each pool and VMs were left at default values. The administrator was shocked that when under a period of heavy CPU usage, the Sales and Finance VMs appeared to drag excessively, yet VM-1 and VM‑2 continued working normally.
