  47           Support hosting fully virtualized guest machines using hardware
  48           virtualization extensions.  You will need a fairly recent
  49           processor equipped with virtualization extensions. You will also
  50           need to select one or more of the processor modules below.
  51
  52           This module provides access to the hardware capabilities through
  53           a character device node named /dev/kvm.

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

  77           (SVM) extensions.
