IIRC, this subject came up earlier this year. I think the conclusion was
that the OS talks to VM and not to the
hardware directly. VM is taking care of the I/O and other "things" (tech
talk) VM 4.4 was 32/64 bit and when an OS was a guest,
VM determined whether it should run 32 or 64.
So, based on that thread, I'm reasonably sure OS/390 2.10 will run under
VM 4.4 on a z9.

We were told that OS/390 2.10 does not run on a z9 but we think the
person might not have realized we were talking about it running under
z/VM 4.4.
