  32   Support hosting fully virtualized guest machines using hardware
  33   virtualization extensions.  You will need a fairly recent
  34   processor equipped with virtualization extensions. You will also
  35   need to select one or more of the processor modules.
  36
  37   This module provides access to the hardware capabilities through
  38   a character device node named /dev/kvm.
