Legacy device assignment has been deprecated since 4.2 (released 1.5 years ago). VFIO is better and everyone should have switched to it. If they haven't, this should convince them. :) Reviewed-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

operating systems inside virtual machines (guests).

This option alone does not add any kernel code.

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.

auditing of KVM MMU events at runtime.
