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

27 Support hosting paravirtualized guest machines using the SIE

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

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