47	  Virtual Machine Extensions are provided in many x86 CPUs. These
48	  provide various facilities for allowing a host OS to provide an
49	  environment where potentially several guest OSes have only
50	  limited access to the underlying hardware. This is achieved
51	  without resorting to software trapping and/or instruction set
52	  emulation (which would be very slow).
53
54	  Intel's implementation of this is called VT-x. This option enables
55	  VT-x this so that the OS that is booted by U-Boot can make use of
56	  these facilities. If this option is not enabled, then the host OS
57	  will be unable to support virtualisation, or it will run very
58	  slowly.
