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

  33           Support hosting fully virtualized guest machines using hardware
  34           virtualization extensions.  You will need a fairly recent
  35           processor equipped with virtualization extensions. You will also
  36           need to select one or more of the processor modules below.
  37
  38           This module provides access to the hardware capabilities through
  39           a character device node named /dev/kvm.

  41           To compile this as a module, choose M here: the module
  42           will be called kvm.

  50           Provides support for KVM on Intel processors equipped with the VT
  51           extensions.

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

  61           (SVM) extensions.
  62
  63           To compile this as a module, choose M here: the module

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