define KernelPackage/kvm-x86/description
  Support hosting fully virtualized guest machines using hardware
  virtualization extensions.  You will need a fairly recent
  processor equipped with virtualization extensions. You will also
  need to select one or more of the processor modules.

  This module provides access to the hardware capabilities through
  a character device node named /dev/kvm.
