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. |
