"Virtualization doesn't really add much of anything for that specific problem other than increased context switching and slightly lower performance." This is BS. What if you have 3 physical servers with 30% utilization? DRS can _seamlessly_ consolidate _arbitrary_ application VMs to one server and shutdown the rest. With bare metal, only certain specifically designed workloads (stateless web farms and some distributed systems etc.) can be moved easily. It seems that dismissing virtualization out of sheer ignorance is a fad these days. Virtualization provides important hardware abstraction to a much wider variety of workloads.
