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