I always use `serial` console for my Qemu hacking but if some cloud
environments rather have viocon's it seems like a sound idea. AFAIK its not
that hard and was on my TODO list when I worked on virtio but it got
sidetracked by other work.

I am currently working on something completely different but might take a
peek but feel free to try :)
