I have not followed the entire discussion. AFAICS this is intended to monitor 
status information on virtio level only, like virtqueue fill status, etc.

One thing that I am looking for is monitoring device specific information 
above virtio level, e.g. certain performance numbers or statistics that only 
make sense for the specific device. That would not fit into any of these 
commands, right?

Best regards,
