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

[Weber, Charles (NIH/NIA/IRP) [C]]

Another thread suggested rolling back both novice and python-websockify.  I had 
first heard about websockify, but it alone made no difference. The combination 
of the 2 with below versions does work.

python-websockify-0.5.1-2.el7.noarch
novnc-0.4-9.el7.noarch

Just trying luck as I have next to none hands-on experience: Could it be
spice/vnc protocol mismatch as opposed to websockets protocol mismatch?
What do websocket proxy logs say?

Adding spice-devel list to the loop as well.

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

[Weber, Charles (NIH/NIA/IRP) [E]]

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
