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