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.

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.

---help---
|
|
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.

---help---

Provides support for KVM on AMD processors equipped with the AMD-V
|
|
(SVM) extensions.

This option adds a R/W kVM module parameter 'mmu_audit', which allows
|
|
audit KVM MMU at runtime.
