Do you mean the zLinux running under zVM couldn't be used for performance
testing purpose, even we dedicate one CPU to this guest machine?
From my point of view, I think it's reasonable... We just don't want to create
a new LPAR with dedicate CPU.
It's an interesting topic! If you were going to test the application
performance on zLinux, what will you do? Install Linux on LPAR directly?

When those other Linux guests are not defined to use the IFL, they
will continue to use the CPs.
I don't think we've ever dedicated CPUs for performance measurements.
The entire motivation for running Linux on z/VM is to share the
resources, so to me measuring the use of dedicated resources is not
interesting. The performance monitor can distinguish overhead and
virtual machine usage.
