  14           This option alone does not add any kernel code.

  39           Support hosting fully virtualized guest machines using hardware
  40           virtualization extensions.  You will need a fairly recent
  41           processor equipped with virtualization extensions. You will also
  42           need to select one or more of the processor modules below.
  43
  44           This module provides access to the hardware capabilities through
  45           a character device node named /dev/kvm.
  46
  47           To compile this as a module, choose M here: the module
  48           will be called kvm.

  56           Provides support for KVM on Intel processors equipped with the VT
  57           extensions.

  59           To compile this as a module, choose M here: the module

  66           Provides support for KVM on AMD processors equipped with the AMD-V
  67           (SVM) extensions.
  68
  69           To compile this as a module, choose M here: the module
