[ovirt-users] console viewing failure after moving engine from CO6 to CO7

Fri Nov 6 19:53:55 UTC 2015

Hi everyone,
I have been moving production Ovirt cluster 4 host+1 engine+FC storage from CentOS 6 to CentOS 7.
I created new cluster with CO7 nodes and did the usual transition without any major issues.
This took care of nodes and worked very well.
I then used the engine backup/restore utility to move engine from old server running CO6 to new server running CO7.
There were the some issues but fairly easily fixed. Mostly CO6 to CO7 stuff like NFS, firewalld etc. To be expected.

However, my web proxy did work with the engine on CO6 and now does not. Local engine console viewer did work on CO6 and now does not.
1.  Hostname is the same
2. errors are different that cert errors
3. restore util should have moved the certs
4. firewall rules are the same as before running iptables

Here are the errors when console is set for novice or spice html5. In both cases web page opens up with black screen and then the error occurs.
novnc
ReferenceError: can’t find variable:WebUtil
spice
Error: Unexpected protocol mismatch

I tried older websockify, no change.

Overt Versions before and after engine move were 3.5.5-1
