16	  Say Y here to get to see options for using your Linux host to run other
17	  operating systems inside virtual machines (guests).
18	  This option alone does not add any kernel code.
19
20	  If you say N, all options in this submenu will be skipped and disabled.

33	  Support hosting fully virtualized guest machines using hardware
34	  virtualization extensions.  You will need a fairly recent
35	  processor equipped with virtualization extensions. You will also
36	  need to select one or more of the processor modules below.
37
38	  This module provides access to the hardware capabilities through
39	  a character device node named /dev/kvm.
40
41	  To compile this as a module, choose M here: the module
42	  will be called kvm.

44	  If unsure, say N.

50	  Provides support for KVM on Intel processors equipped with the VT
51	  extensions.

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