I tried this very '-device' line and I can see that the guest has loaded
the virtio modules, but there isn't anything in the virtio0 directory other

Is there a way to debug this?
Something possibly related is that, I had to rewind the tree by some commits
because this series doesn't apply against current HEAD.
