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