  12           Say Y here to get to see options for using your Linux host to run other
  13           operating systems inside virtual machines (guests).
  14           This option alone does not add any kernel code.

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

  38           If unsure, say N.

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