12 Say Y here to get to see options for using your Linux host to run other
13 operating systems inside virtual machines (guests).
14 This option alone does not add any kernel code.
16 If you say N, all options in this submenu will be skipped and disabled.

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

61 Provides support for KVM on Intel processors equipped with the VT
64 To compile this as a module, choose M here: the module
65 will be called kvm-intel.

71 Provides support for KVM on AMD processors equipped with the AMD-V
74 To compile this as a module, choose M here: the module
75 will be called kvm-amd.
79 depends on KVM && TRACEPOINTS
81 This option adds a R/W kVM module parameter 'mmu_audit', which allows
82 audit KVM MMU at runtime.

86 depends on KVM && PCI && IOMMU_API
89 Provide support for legacy PCI device assignment through KVM. The
90 kernel now also supports a full featured userspace device driver
91 framework through VFIO, which supersedes much of this support.
95 # OK, it's a little counter-intuitive to do this, but it puts it neatly under
96 # the virtualization menu.
