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

  43          Support hosting fully virtualized guest machines using hardware
  44          virtualization extensions.  You will need a fairly recent
  45          processor equipped with virtualization extensions. You will also
  46          need to select one or more of the processor modules below.
  47
  48          This module provides access to the hardware capabilities through
  49          a character device node named /dev/kvm.
  50
  51          To compile this as a module, choose M here: the module
  52          will be called kvm.

  54          If unsure, say N.

  62          Provides support for KVM on Intel processors equipped with the VT
  63          extensions.

  65          To compile this as a module, choose M here: the module
  66          will be called kvm-intel.

  70        depends on KVM
  71        ---help---
  72          Provides support for KVM on AMD processors equipped with the AMD-V
  73          (SVM) extensions.
  74
  75          To compile this as a module, choose M here: the module
  76          will be called kvm-amd.

  82         This option adds a R/W kVM module parameter 'mmu_audit', which allows
  83         audit  KVM MMU at runtime.
