[Tomokazu Hirai]

I can not view console on noVNC display.

there is no error at /var/log/nova-consoleauth.log and I can view noVNC display, but display is all gray...
Gray bar includes such message.

    noVNC ready: native WebSockets, canvas rendering

I found a zombie process of nova-novncproxy.

nova 24982 0.0 0.7 134340 32328 ? Ss 20:22 0:00 /usr/bin/python /usr/bin/nova-novncproxy --config-file=/etc/nova/nova.conf

now I use ubuntu cloud archive package (2013.2-0ubuntu1~cloud0)

As far as I can see here, this is not a horizon bug. Nova novnc is part of nova.

[Russell Bryant (russellb)]

Can you replicate this with the latest code?

This could be the fault of the image you were using. What image?

[Haomeng,Wang (whaom)]

This is not an invalid bug, I encountered same issue, try to debug, fond novaproxy try to connect to '-1' port as the console default port, that should be incorrect port number, I think that should be root cause, but not sure why is it.

[Julie Pichon (jpichon)]

Horizon gets the URL (including the port) from nova get-vnc-console, which I believe is defined in the nova.conf file

[Hassaan (hassaan)]

1)Open rfb.js file in the editor of your control node located at : /usr/share/novnc/include/rfb.js
2)Find def_con_timeout variable in the file
3) Increase the timeout interval (i changed it to 200:500)
4)Save and exit
5)Restart the noVNC service by following command:
service openstack-nova-novncproxy restart
