+          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 can only emulate
+          POWER5+, POWER6 and POWER7 processors.
+
+          This module provides access to the hardware capabilities through
+          a character device node named /dev/kvm.
