This kernel module can be loaded in host kernel to accelerate
|

guest networking with virtio_net. Not to be confused with virtio_net
|
||||
module itself which needs to be loaded in guest kernel.

define KernelPackage/irqbypass/description
|
||||
Various virtualization hardware acceleration techniques allow bypassing or
|
||||
offloading interrupts received from devices around the host kernel. Posted
|
||||
Interrupts on Intel VT-d systems can allow interrupts to be received
|
||||
directly by a virtual machine. ARM IRQ Forwarding allows forwarded physical
|
||||
interrupts to be directly deactivated by the guest. This manager allows
|
||||
interrupt producers and consumers to find each other to enable this sort of
|
||||
bypass.

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.
|
||||
|
||||
This module provides access to the hardware capabilities through
|
||||
a character device node named /dev/kvm.
