Virtio drivers on jetson nano

Hi all,

I needed some info on virtio drivers for jetson nano. I found a couple of kernel configurations for virtio.

The help for virtio net host driver says it improves performance of guest networking. What should be done at qemu or in guest kernel to get this improved performance ?

Second is the virtio gpu driver. I could not get info anywhere what its purpose is.

I have qemu built with virgl renderer and I run with qemu options: -device virtio-gpu-pci,virgl=on,xres=1600,yres=900 -display sdl,gl=on

which is working fine. Is there a scope for further improvement ?
