source "virt/kvm/Kconfig"
menuconfig VIRTUALIZATION
bool "Virtualization"
depends on HAVE_KVM || X86
default y
Say Y here to get to see options for using your Linux host to run other
operating systems inside virtual machines (guests).
This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.
if VIRTUALIZATION
config KVM
tristate "Kernel-based Virtual Machine (KVM) support"
depends on HAVE_KVM

select HAVE_KVM_MSI
select HAVE_KVM_CPU_RELAX_INTERCEPT
select KVM_VFIO
Support hosting fully virtualized guest machines using hardware
virtualization extensions. You will need a fairly recent
processor equipped with virtualization extensions. You will also
need to select one or more of the processor modules below.
This module provides access to the hardware capabilities through
a character device node named /dev/kvm.
To compile this as a module, choose M here: the module
will be called kvm.
If unsure, say N.
config KVM_INTEL
tristate "KVM for Intel processors support"
depends on KVM
depends on CPU_SUP_INTEL
Provides support for KVM on Intel processors equipped with the VT
extensions.
To compile this as a module, choose M here: the module
will be called kvm-intel.
config KVM_AMD
tristate "KVM for AMD processors support"
depends on KVM
Provides support for KVM on AMD processors equipped with the AMD-V
(SVM) extensions.
To compile this as a module, choose M here: the module
will be called kvm-amd.
config KVM_MMU_AUDIT
bool "Audit KVM MMU"
depends on KVM && TRACEPOINTS
This option adds a R/W kVM module parameter 'mmu_audit', which allows
auditing of KVM MMU events at runtime.
config KVM_DEVICE_ASSIGNMENT
bool "KVM legacy PCI device assignment support"
depends on KVM && PCI && IOMMU_API
default y
Provide support for legacy PCI device assignment through KVM. The
kernel now also supports a full featured userspace device driver
framework through VFIO, which supersedes much of this support.
If unsure, say Y.

source drivers/lguest/Kconfig
