36	  Virtual Machine Extensions are provided in many x86 CPUs. These
37	  provide various facilities for allowing a host OS to provide an
38	  environment where potentially several guest OSes have only
39	  limited access to the underlying hardware. This is achieved
40	  without resorting to software trapping and/or instruction set
41	  emulation (which would be very slow).
42
43	  Intel's implementation of this is called VT-x. This option enables
44	  VT-x this so that the OS that is booted by U-Boot can make use of
45	  these facilities. If this option is not enabled, then the host OS
46	  will be unable to support virtualisation, or it will run very
47	  slowly.
