Description

Hi, I am using the console feature on 1.9 to look into node on the oVirt compute resource. I get a blank screen on several browsers so I enabled debugging and looked around.

Here is what I have done so far:
  • installed foreman
  • added ec2, oVirt and Vmware compute resources
  • disabled SELinux (was getting a connection refused error message)
  • in firefox, went to about:config and modified network.websocket.allowInsecureFromHTTPS to true

This is the output of /var/log/foreman/production.log after clicking on the "Console" button:

Attempted to start a console on a node in vcenter, and get a similar reaction:

and simliar to the other, the process starts:

This time, however, there is a banner which appears at the top of the console window that says, "WebSock error: [object Event]", in red.

sorry for the double update, but the last "hqesx3.corp.practicefusion.com" should read "hqesx3.hq.practicefusion.com" - it was a typeo on my part

From the logs it seems everything is working correctly. Foreman can occasionally spawn extra process if the port was already in use. Make sure the certificate is the one that your Foreman application use. Also verify if the target responds correctly (e.g. 10.12.17.195:5903). Try to telnet there from the Foreman server.
