please check bug https://bugzilla.redhat.com/show_bug.cgi?id=2005221

seems we ended up with a nasty bug in 4.4.8, We will be releasing 4.4.8.6 shortly, but it won’t fix the problem for those who already upgraded.

If you have a Windows VM, can you please check "Hardware Clock Time Offset” in Edit VM/System, whther it has default GMT or a different value that you have set before - assuming that you did. For Windows people usually set it to their local time zone.

For the HE problem, can you try to actually edit that VM and change something (something that’s changeable, e.g. description) and save it? 
Regardless if that works, can you try to restart HE (by moving to global maintenance, or if you don’t care too much, just shut it down from within that HE VM and let it be restarted automatically)

If you have any additional logs/observation please add that to the bug

Thanks,
michal

Dear all,
I have just updated my ovirt installation, with self hosted engine, from 4.4.5 to 4.4.8.5-1.
Everything went smoothly and in a few minutes the system was back up and running.
A little issue is still puzzling me.
I am asked to update from 4.5 to 4.6 the cluster and data center compatibility level. When I try to issue the command from the cluster config I get this error:

Error while executing action: Cannot update cluster because the update triggered update of the VMs/Templates and it failed for the following: HostedEngine. To fix the issue, please go to each of them, edit, change the Custom Compatibility Version (or other fields changed previously in the cluster dialog) and press OK. If the save does not pass, fix the dialog validation. After successful cluster update, you can revert your Custom Compatibility Version change (or other changes). If the problem still persists, you may refer to the engine.log file for further details.

It's very strange because the config of the hostedengine is "plain" and there are no constrains on compatibility version, as you can see in this picture:

In any case, if I try to force compatibility with 4.6 I get this error:

Error while executing action:

HostedEngine:

    There was an attempt to change Hosted Engine VM values that are locked.

So I am stuck. Not a big deal at the moment, but sooner or later I will have to do this upgrade and I don't know where I am wrong.

Can anybody give a clue?
Thanks in advance,


Andrea
