This is an old version of spice server. You need to build the current
git master of the server on the host (note as Uri correctly commented
the name of the virtio port was recently changed, if you get the latest
master, you'll be fine).

With your version of the spice server, the server doesn't open the
other side of the virtio port, that's why you're not getting anything.

Cheers,
Lukas
