13 operating systems inside virtual machines (guests).
14 This option alone does not add any kernel code.

35 Support hosting fully virtualized guest machines using hardware
36 virtualization extensions. You will need a fairly recent
37 processor equipped with virtualization extensions. You will also
38 need to select one or more of the processor modules below.

40 This module provides access to the hardware capabilities through
41 a character device node named /dev/kvm.
42
43 To compile this as a module, choose M here: the module
44 will be called kvm.

52 Provides support for KVM on Intel processors equipped with the VT
53 extensions.
