Does this include the RAM for the VM? For auto-idle systems like this where to park the RAM tends to be a significant concern. If you don't "retire" the RAM too the idling savings are limited to CPU cycles but if you do, the overheads of moving RAM around can easily wreck any latency budget you may have.

Curious how you are dealing with it.
