  13           operating systems inside virtual machines (guests).
  14           This option alone does not add any kernel code.

  35           Support hosting fully virtualized guest machines using hardware
  36           virtualization extensions.  You will need a fairly recent
  37           processor equipped with virtualization extensions. You will also
  38           need to select one or more of the processor modules below.
  39
  40           This module provides access to the hardware capabilities through
  41           a character device node named /dev/kvm.

  43           To compile this as a module, choose M here: the module
  44           will be called kvm.

  63           (SVM) extensions.
