+	  Virtual Machine Extensions are provided in many x86 CPUs. These
+	  provide various facilities for allowing a host OS to provide an
+	  environment where potentially several guest OSes have only
+	  limited access to the underlying hardware. This is achieved
+	  without resorting to software trapping and/or instruction set
+	  emulation (which would be very slow).
+
+	  Intel's implementation of this is called VT-x. This option enables
+	  VT-x this so that the OS that is booted by U-Boot can make use of
+	  these facilities. If this option is not enabled, then the host OS
+	  will be unable to support virtualisation, or it will run very
+	  slowly.
