a few of our s/w products drill down to the model number
not just the serial #, but all that could not be done prior had grace
periods
or so called emerg keys

z/VM can set a guest's CPU serial to any value. This works to "fool"
only a subset of software.

AFAIK, the CPU type cannot be changed under z/VM.

And, these days much software looks at the output of STSI (or CSRSI),
QVS, LPDAT, DIAG 204, and other sources to get capacity information.
