+
+ 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
