  10          Say Y here to get to see options for using your Linux host to run
  11          other operating systems inside virtual machines (guests).
  12          This option alone does not add any kernel code.
  13
  14          If you say N, all options in this submenu will be skipped and
  15          disabled.

  27          Support hosting virtualized guest machines. You will also
  28          need to select one or more of the processor modules below.
  29
  30          This module provides access to the hardware capabilities through
  31          a character device node named /dev/kvm.

  33          If unsure, say N.

  48          Static number of max supported virtual CPUs per VM.
  49
  50          If you choose a high number, the vcpu structures will be quite
  51          large, so only choose a reasonable number that you expect to
  52          actually use.
