config HAVE_KVM

menuconfig VIRTUALIZATION
bool "Virtualization"
depends on HAVE_KVM || X86
default y
---help---
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
# for device assignment:
depends on PCI
select PREEMPT_NOTIFIERS
select MMU_NOTIFIER
select ANON_INODES
---help---
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
---help---
Provides support for KVM on Intel processors equipped with the VT
extensions.
config KVM_AMD
tristate "KVM for AMD processors support"
depends on KVM
---help---
Provides support for KVM on AMD processors equipped with the AMD-V
(SVM) extensions.
config KVM_TRACE
bool "KVM trace support"
depends on KVM && MARKERS && SYSFS
select RELAY
select DEBUG_FS
default n
---help---
This option allows reading a trace of kvm-related events through
relayfs. Note the ABI is not considered stable and will be
modified in future updates.
# OK, it's a little counter-intuitive to do this, but it puts it neatly under
# the virtualization menu.
