help
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.
