And your focus would be the z/VM 3.1 guest first. The z/VM 5 system is
happy to give available resources to the guest if it is asking for it,
unless you told them otherwise. My guess is that something there
started to misbehave. Probably unrelated to the actual hardware
change, but triggered by the IPL.
Normally doing a few times #CP IND QUEUE on the z/VM 3.1 system would
point you at the guilty user. If not, then we'd be happy to look at
raw data from the z/VM 3.1 guest if you can capture that (we can talk
off-line to discuss how to transfer the data).
