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.

Provides support for KVM on Intel processors equipped with the VT

extensions.

will be called kvm-intel.

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.

|

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

---help---
|
|
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 this support and provides
|
|
better security.
|

If unsure, say N.
