└─>KVM support for POWER7 and PPC970 using hypervisor mode in host
In linux kernel since version 3.1 (release Date: 2011-10-24)
Support running unmodified book3s_64 guest kernels in
virtual machines on POWER7 and PPC970 processors that have
hypervisor mode available to the host.
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.
If unsure, say N.
