Yes! It would be great to see other vendors using Virtio. I have not done any performance tuning yet though, so I guess the only unknown factor is the overhead. But since Virtio is already used in virtualized environments I believe that some optimization has been done already. If that's not enough then future virtio specific driver optimizations can be benefit both enterprise and embedded. Thanks, / magnus
