Answering the question for posterity.
We found a temporary solution to the described problem.
We had an oVirt development cluster with a working SPICE console. By 
comparing packages we have established the differences between working 
and not working SPICE setup. We have isolated the spice-server package.
The installed version was spice-server-0.14.0-2.el7_5.3.x86_64
We downgraded the package to spice-server-0.12.8-2.el7.1.x86_64 and 
rebooted the nodes in sequence.
Now the SPICE console works again.

Kind regards,
Mitja
