You are exhibiting a z/OS bias!
z/VM "waits" with a CPU loop (so it doesn't need to come out of a wait state
when it is waiting) so it would run just as hot when it was idle as otherwise.
(Unless there is special code to account for machine perspiration?)
I've been running z/VM for decades. When "idle", a z/VM image uses far,
far, *far* less CPU than an idle z/OS. Almost zero. It's definitely in a
traditional wait state. If this were not a text-only list, I would post
JPEGs of various displays from my z9 HMC as evidence.
