I can see two different "VMs". I say "VMs" because it could be the same
code with different magic numbers to control its behavior.

balance is three way here between interactive response, disk throughput

Perhaps having a VM system that you select your main focus server vs
desktop would be the way to go. Also the end-user should be able to adjust
this balance. Say a person selected desktop, and is a graphic artist, they
may not care as much about network thoroughput and rather push up
interactive response and disk throughput at the expense of the network
thoroughput.
