Ah, right, yes, if you do not have anything else running then it’s failing on 
one of those Down VMs. If you have a lot of them a direct db query might be 
fastest to find out (we’re still working on improvement to log the actual VM 
name that failed)

The problem is that it is the hosted-engine itself that is blocking the
upgrade. There is only one VM running but maybe there is one of the
shutdown VMs that is blocking this. Will have a look at all of them and
save their config to see if that helps.

Is that an old VM, perhaps from 3.5 or even earlier? Has it been restarted 
since? Can you shut it down now and rerun after the cluster change? That would 
likely be the most simple resolution.
If there are troubles even after the VM is Down try to edit and swithc console 
from VNC to SPICE or vice versa and run again

[ovirt-users] Cluster upgrade from 3.6 to 4.1 fails

[jvdwege]

As per the subject I'm trying to upgrade my ovirt install and sofar the
upgrade has been smooth.
I'm running hosted-engine in Centos7.3 and my hosts are running Fedora24
now with ovirt-4.1
If I try to upgrade my cluster from version 3.6 to 4.0 or 4.1 I receive
an error message and can't find a solution using google. First I get the
following message:

All running VMs will be temporarily reconfigured to use the previous
cluster compatibility version and marked pending configuration change.
 In order to change the cluster compatibility version of the VM to a new
version, the VM needs to be manually shut down and restarted.
 There are 1 running VM(s) affected by this change.

 Are you sure you want to change the Cluster Compatibility Version?

Yes, I want to change version :-) so I click OK 
I then get the following error message: 

Error while executing action: 

* Cannot edit Cluster. Illegal number of monitors is provided, max
allowed number of monitors is 1 for VNC and the max number in the
ValidNumOfMonitors configuration variable for SPICE.
* Cannot edit VM. Illegal number of monitors is provided, max allowed
number of monitors is 1 for VNC and the max number in the
ValidNumOfMonitors configuration variable for SPICE.

Anyone has seen this before and is able to help? 

Thanks,
