vhost-net is used to accelerate traffic to virtualisation
guests that use the virtio-net network card in QEMU.
Generally it is invoked by specifying "vhost=on" to a
QEMU -netdev device:
qemu-system-aarch64 -nographic -M virt -cpu host \
--enable-kvm -bios u-boot.bin -smp 1 -m 2048 \
-drive file=openwrt-armsr-armv8.img,format=raw,index=0,media=disk \
-device "virtio-net,netdev=landev,disable-legacy=off,disable-modern=off" \
-netdev "tap,id=landev,helper=/usr/lib/qemu-bridge-helper --br=br-lan,vhost=on"

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.
