37edf88417SAvi Kivity	  Support hosting fully virtualized guest machines using hardware
38edf88417SAvi Kivity	  virtualization extensions.  You will need a fairly recent
39edf88417SAvi Kivity	  processor equipped with virtualization extensions. You will also
40edf88417SAvi Kivity	  need to select one or more of the processor modules below.
41edf88417SAvi Kivity
42edf88417SAvi Kivity	  This module provides access to the hardware capabilities through
43edf88417SAvi Kivity	  a character device node named /dev/kvm.

45edf88417SAvi Kivity	  To compile this as a module, choose M here: the module
46edf88417SAvi Kivity	  will be called kvm.
