  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.

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

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