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

Fri Jun 14 15:45:55 UTC 2013

Hi Matt!

Right now I'm not sure whether you are trying to launch console via MIME (i.e. the console.vv is served to your locally installed virt-viewer) or you want to run noVNC html client. (I'm a little bit confused because the $subj contains noVNC but console.vv is actually the MIME way.)

The noVNC client is now in the engine, but it runs only via plain http out of the box (for the moment). If you want to use it, you must ensure two things:
 1, You must run ovirt-websocket-proxy (preferably on the machine where the engine runs) - just use ovirt-websocket-proxy package and run the service.
 2, You must configure the engine so that it knows that you want to use noVNC instead of MIME invocation. You can do it in the database or using the tools via WebSocketProxy option. If your websocket-proxy runs on the engine, set it to 'Engine:xyz', where xyz is the port on which the proxy runs (6100 is the default now).

Regards,
Frank.

Hi Alon,

I have stopped there, but I get a console.vv download again on my Firefox
and no console!

Cheers,

Matt
