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.

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