Hi,

We upgraded one of our infrastructures to 4.2.0 recently and since then some of our 
machines have the "Console" button greyed-out in the Admin UI, like they were 
disabled.

I changed their compatibility to 4.2 but with no luck, as they're still 
disabled.

Is there a way to know why is that, and how to solve it?

I'm attaching a screenshot.
Hi Nicolas.
I had the same problem with most of my VMs after the upgrade from 4.1 to 4.2.
See bugzilla here:https://bugzilla.redhat.com/show_bug.cgi?id=1528868
(which admittedly was a mesh of a bunch of different issues that occurred)
yeah, that’s not a good idea to mix more issues:)
Seemshttps://bugzilla.redhat.com/show_bug.cgi?id=1528868#c26  is the last one 
relevant to the grayed out console problem in this email thread.

it’s also possible to check "VM Devices” subtab and list the graphical devices. 
If this is the same problem as from Nicolas then it would list cirrus and it would 
be great if you can confirm the conditionas are similar (i.e. originally a 3.6 VM)
I believe it was originally a 3.6 VM. Is there anywhere I can verify this info? If not, it would be helpful if oVirt kept track of the version that created the VM for cases just like this.

Hi,
well, we keep the date and who did that, but we can’t really keep all the logs forever. Well, you can if you archive them somewhere, but I guess that’s impractical for such a long time:-D

I wasn't really thinking in terms of logs. I was thinking a database field that tracks the ovirt version that created the VM.


 VM Device subtab: (no Cirrus)

so this is a screenshot from VM where the button is grayed out when you start it?
Hm..it doesn’t look wrong.

Yes.

And then - if possible - describe some history of what happened. When was the 
VM created, when was cluster updated, when the system was upgraded and to what 
versions.
All I know is that everything was working fine, then I updated to 4.2, updated cluster version, and then most of my consoles were not available. I can't remember if this happened before the cluster upgrade or not. I suspect it was most and not all VMs since some of them had been created later than 3.6, and this was an older one. I only have this one VM left in this state because I had deleted the other VMs and recreated them one at a time... I will wait to see if you want me to try Vineet's solution of making it headless,

Thanks.
Can you get engine.log and vdsm log when you attempt to start that VM ? just the relevant part is enough.

Sure.. I restarted the VM (called "rs").

engine.log: http://www.eecs.yorku.ca/~jas/ovirt-debug/02202018/engine.log

vdsm log: http://www.eecs.yorku.ca/~jas/ovirt-debug/02202018/vdsm.log

Jason.
