  11           other operating systems inside virtual machines (guests).
  12           This option alone does not add any kernel code.

  45           Static number of max supported virtual CPUs per VM.
  46
  47           If you choose a high number, the vcpu structures will be quite
  48           large, so only choose a reasonable number that you expect to
