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