Hi Xuan,
I'm actually working on a VirtIO compatible DPU, no virtualization at
all, so I wasn't planning on implementing it in qemu or vhost.

I have some more development plans for the VirtIO spec and for the
linux kernel in virtio-net (and maybe virtio-blk).
Adding a timeout to the control vq is one example (needed with
physical VirtIO devices).

I would of course help to implement the notifications coalescing
feature in qemu/vhost if you need.
