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