In the guest I wouldn't want virtio-serial devices to be mixed up with
the virtio-console device. virtio-console has nice clear usecase of
being an interactive console, and as such the guest OS can & should
automatically start a mingetty/agetty process on any virtio-console
device it finds. If we use virtio-console for data channels to, then
guest config becomes much harder todo automatically.
By all means share underlying code/infrastructure where appropriate,
but they must ultimately appear as clearly separate devices IMHO
