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

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

  60        ---help---
  61          Provides support for KVM on Intel processors equipped with the VT
  62          extensions.
  63
  64          To compile this as a module, choose M here: the module
  65          will be called kvm-intel.

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

  81         This option adds a R/W kVM module parameter 'mmu_audit', which allows
  82         audit  KVM MMU at runtime.
  83
  84config KVM_DEVICE_ASSIGNMENT

  88        ---help---
  89          Provide support for legacy PCI device assignment through KVM.  The
  90          kernel now also supports a full featured userspace device driver
  91          framework through VFIO, which supersedes much of this support.
  92
  93          If unsure, say Y.
  94
  95# OK, it's a little counter-intuitive to do this, but it puts it neatly under
  96# the virtualization menu.
