[Users] oVirt 3.3 does not start HTML5/noVNC viewer

I suppose this could be more of a problem with init script than with proxy itself.
Could you try running proxy without using service? i.e. go to the directory where the proxy is installed (should be /usr/share/ovirt-engine/services and run the proxy from there using './ovirt-websocket-proxy.py start'). What's the output?

Thanks,
F.
