46 | Support hosting fully virtualized guest machines using hardware | |
47 | virtualization extensions. You will need a fairly recent | |
48 | processor equipped with virtualization extensions. You will also | |
49 | need to select one or more of the processor modules below. | |
50 | ||
51 | This module provides access to the hardware capabilities through | |
52 | a character device node named /dev/kvm. | |

54 | To compile this as a module, choose M here: the module | |
55 | will be called kvm. | |
