Original GitHub issue: https://github.com/retspen/webvirtmgr/issues/429

When using SSH connection type with webvirtmgr, noVNC tries to connect to hostname:ssh-port:vnc-port:

-bash-4.1$ python .../webvirtmgr/console/webvirtmgr-novnc
WARNING:root:No local_settings file found.
WebSocket server settings:
    - Listen on 0.0.0.0:6080
    - Flash security policy server
    - SSL/TLS support
    - proxying from 0.0.0.0:6080 to ignore:ignore

1: 192.168.x.x: SSL/TLS (wss://) WebSocket connection
1: 192.168.x.x: Version hybi-13, base64: 'True'
1: connecting to: foo.bar.tld:xxxx:59xx
1: handler exception: [Errno -2] Name or service not known

As a workaround I've modified .../webvirtmgr/console/webvirtmgr-novnc on line 74 to be:

tsock = socket_factory("hostname-without-ssh-port", port, connect=True)

After restarting supervisor(d) or webvirtmgr-novnc, noVNC then connects normally.

Mmh, I had the same problem, now with this fix I get:

WebSocket server settings:
   - Listen on 0.0.0.0:6080
   - Flash security policy server
   - SSL/TLS support
   - proxying from 0.0.0.0:6080 to ignore:ignore

   1: 192.168.10.94: Plain non-SSL (ws://) WebSocket connection
   1: 192.168.10.94: Version hybi-13, base64: 'False'
   1: handler exception: 'NoneType' object has no attribute 'find'

Do you restart webvirtmgr-novnc after update?

Yes, it's a fresh start (from command line, no init script) after restarting supervisor

Nevermind, it was a secret key problem (I had a parallel installation in another path with pip and it was trying to read that secret key). Sorry for the noise and great software BTW!
