If you say Y here, KVM will use the hardware virtualization

|
facilities of POWER7 (and later) processors, meaning that
|
|
guest operating systems will run at full hardware speed
|
|
using supervisor and user modes. However, this also means
|
|
that KVM is not usable under PowerVM (pHyp), is only usable
|
|
on POWER7 (or later) processors and PPC970-family processors,
|

and cannot emulate a different processor from the host processor.
