27 Support hosting fully virtualized guest machines using hardware
28 virtualization extensions. You will need a fairly recent
29 processor equipped with virtualization extensions. You will also
30 need to select one or more of the processor modules below.
31
32 This module provides access to the hardware capabilities through
33 a character device node named /dev/kvm.
34
35 To compile this as a module, choose M here: the module
36 will be called kvm.
