29 Support hosting fully virtualized guest machines using hardware
30 virtualization extensions. You will need a fairly recent
31 processor equipped with virtualization extensions. You will also
32 need to select one or more of the processor modules below.

34 This module provides access to the hardware capabilities through
35 a character device node named /dev/kvm.

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