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

  36           Support hosting fully virtualized guest machines using hardware
  37           virtualization extensions.  You will need a fairly recent
  38           processor equipped with virtualization extensions. You will also
  39           need to select one or more of the processor modules below.

  41           This module provides access to the hardware capabilities through
  42           a character device node named /dev/kvm.
  43
  44           To compile this as a module, choose M here: the module
  45           will be called kvm.

  54           extensions.

  63           Provides support for KVM on AMD processors equipped with the AMD-V
  64           (SVM) extensions.
  65
  66           To compile this as a module, choose M here: the module
