Symptoms
After Odin Automation upgrade to 7.2 version, VE console stops working for all Virtual Environments on a particular Virtuozzo 6.0 hardware node.
The state of "Remote Display" for such VEs is STOPPED, while it's configured in automatic mode:
[root@vz01 ~]# prlctl list -i 1000010.example
INFO
...
Remote display: mode=auto address=0.0.0.0
Remote display state: stopped
...
Note: Please use correct VE name (could be different from a hostname) or VE uuid instead.
Cause
The cause behind the discrepancy of the state of VNC server (auto + stopped) lies on Virtuozzo level. OACI does not handle such combination of states. The behavior is planned to be improved in scope of internal request CCU-17448.
Resolution
Disable VNC automatic mode for all VEs on the node:
# for i in `prlctl list -Hao uuid`; do prlctl set $i --vnc-mode off; done
This should make the console operable in Customer's CP.
