  14          This option alone does not add any kernel code.

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

  52          If unsure, say N.

  61          extensions.

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

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

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