Thanks Daniel!! That is significant.
The customer needs to have OS/390 available to support their customers, so
the ability to run 2.10 on a z9 (as a zVM guest) is a major concern.
And Alan A..... Your information is welcomed also, but I understand that
there is a difference between what IBM "supports" and what will run...
For example, IBM does provide a 'patch' for VSE 2.3 to run on a z9, and it
does work, but I'm sure that it is not 'supported' by IBM. I also
believe/understand that there are 'fixes' to allow 2.10 to run on a z9
(under VM) although it would not be 'supported'... Daniel's experience
helps to confirm this belief...

Subject: OS/390 as zVM 5.2 Guest on z9 ??
Is anyone out there running OS/390 2.9 (or earlier) as a guest of zVM
(5.2 in my case, but probably does not matter) on a z9 ??
I'm trying to migrate a customer from a FLEX system to a z9 and they
have an old, "un-maintained" OS/390 2.9 guest. It was running as a VM
guest with dedicated disks on the FLEX system (zVM 4.4). I've brought
everything over to the z9 and converted the disks to full-pack minidisks
to
(hopefully) eliminate problems related to using the DS6800 subsystem.
Other than the full-pack minis vs. dedicated, I believe everything is
the same. However, when I try to IPL OS/390, it runs for a while (say,
15
seconds) then gets:
HCPGIR453W CP entered; program interrupt loop
I know this can sometimes be an 'architectural' type problem and I'm
just afraid it may be this time.
I have verified that the OS/390 IPL does run a while... it gets to
processing the IPLPARM. (If I specify an invalid IPLPARM I get an
appropriate wait state code loaded.) So I know it is at least running
for a little while.
Any suggestions out there??
