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.

endef
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.

define KernelPackage/kvm-x86/description
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.
