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

  15           If you say N, all options in this submenu will be skipped and

  31           440 host processors.

  33           This module provides access to the hardware capabilities through

  42           Calculate elapsed time for every exit/enter cycle. A per-vcpu
  43           report is available in debugfs kvm/vm#_vcpu#_timing.
  44           The overhead is relatively small, however it is not recommended for
  45           production environments.

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