Do you not control whether a Linux guest is dispatched on IFLs or regular CPUs via the directory? If a guest can only run on IFLs and not regular CPUs because of this, do the license fees increase if a Linux workload is melded in with a regular workload instead of running it in a separate LPAR?
When did the IFL become faster than a regular CPU?
