46*4882a593Smuzhiyun	  Virtual Machine Extensions are provided in many x86 CPUs. These
47*4882a593Smuzhiyun	  provide various facilities for allowing a host OS to provide an
48*4882a593Smuzhiyun	  environment where potentially several guest OSes have only
49*4882a593Smuzhiyun	  limited access to the underlying hardware. This is achieved
50*4882a593Smuzhiyun	  without resorting to software trapping and/or instruction set
51*4882a593Smuzhiyun	  emulation (which would be very slow).
52*4882a593Smuzhiyun
53*4882a593Smuzhiyun	  Intel's implementation of this is called VT-x. This option enables
54*4882a593Smuzhiyun	  VT-x this so that the OS that is booted by U-Boot can make use of
55*4882a593Smuzhiyun	  these facilities. If this option is not enabled, then the host OS
56*4882a593Smuzhiyun	  will be unable to support virtualisation, or it will run very
57*4882a593Smuzhiyun	  slowly.
