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

  30           Support hosting fully virtualized guest machines using hardware
  31           virtualization extensions.  You will need a fairly recent
  32           processor equipped with virtualization extensions. You will also
  33           need to select one or more of the processor modules below.
  34
  35           This module provides access to the hardware capabilities through
  36           a character device node named /dev/kvm.
  37
  38           To compile this as a module, choose M here: the module
  39           will be called kvm.

  47           Provides support for KVM on Intel processors equipped with the VT
  48           extensions.

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

  57           Provides support for KVM on AMD processors equipped with the AMD-V
  58           (SVM) extensions.
  59
  60           To compile this as a module, choose M here: the module
  61           will be called kvm-amd.

  71           This option allows reading a trace of kvm-related events through
  72           relayfs.  Note the ABI is not considered stable and will be
  73           modified in future updates.
