16	  If you say N, all options in this submenu will be skipped and disabled.

40	  Support hosting fully virtualized guest machines using hardware
41	  virtualization extensions.  You will need a fairly recent
42	  processor equipped with virtualization extensions. You will also
43	  need to select one or more of the processor modules below.
44
45	  This module provides access to the hardware capabilities through
46	  a character device node named /dev/kvm.
47
48	  To compile this as a module, choose M here: the module
49	  will be called kvm.

51	  If unsure, say N.

59	  Provides support for KVM on Intel processors equipped with the VT
60	  extensions.

62	  To compile this as a module, choose M here: the module
63	  will be called kvm-intel.

79	 This option adds a R/W kVM module parameter 'mmu_audit', which allows
80	 audit  KVM MMU at runtime.
