Here's an educated guess based on the way we define an ICF (Integrated
Coupling Facility). Pick the mode you want (Linux only) on the General tab.
Then on the Processor tab, select something like 'Linux only' analogous to
the way we select 'CF only' for an ICF.
For ICF and I believe for Linux, you could choose to run that mode in an
LPAR and share CPs with MVS. You don't want to do that in this case, but
the way you avoid it is in the processor options.

Please respond
to Linux on 390
Port
Gordon:
Choose "Linux only". You might as well dedicate the processor, unless
you want to create a test LPAR.
