Hello Adam,
I was part of the developers group. I thought it was neat that
you could. But there were some major problems running
Hercules-VM/ESA-VSE/ESA. I did learn lots.
But IBM was extremely hostile.

Your answer was probably complicated by the fact that when you asked
the question, IBM very likely assumed an implied "on commodity
hardware."
So I think we need to ask a followup question: "...on Hercules, when
running in a z/Linux image, underneath an instance of z/VM on the
processor or processors to which that version z/VM is licensed."
Certainly no one ever told me what I was doing on my H70 was illegal.
A lot of people asked me questions that implied that they thought I
was an idiot or at least insane--which, you know, from a performance
standpoint, well, yeah, guilty as charged--but no one said that I
shouldn't run my copy of z/VM at about 1/100th speed if that was what
I really wanted to do.
Adam
