No. Those are *virtual* CPU definitions.

The 1st option is if you are running in an LPAR with mixed CPU types, CP
IFL. The first option ensures that your Linux guest runs on an IFL. By
default it will run on a CP.

Thank you all very much for the great assistance.
Now, to continue the quote from Casablanca, Where are my winnings?
I will pop a note as suggested.

On our
system, the first real IFL is CPU 02 (00 and 01 are
a
WAS/Linux workload and could see the work only dispatching on the CP's.
I will report back when we get more info.
