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

  36           Support hosting paravirtualized guest machines using the SIE
  37           virtualization capability on the mainframe. This should work
  38           on any 64bit machine.

  40           This module provides access to the hardware capabilities through
  41           a character device node named /dev/kvm.

  43           To compile this as a module, choose M here: the module
  44           will be called kvm.
