OpenStack Compute (nova)

Folsom: novnc is not working, not able to access VNC of the instances. Error: Failed to connect to server (code: 1006)

Asked by Srikanth Mergu on 2013-07-04

Hello,

I have installed Folsom (1Controller & 2 Compute servers ) on 3 Cento's Boxes. Everything is working fine except VNC. As it is in production from past 5 months. Now i am in deep trouble with one of the instance. I want to boot that instance in single user mode to recover that instance, for that i need to fix VNC on Compute Nodes. Kindly help me in fixing this issues.
