<div class="pre" style="margin: 0; padding: 0; font-family: monospace">As per the subject I'm trying to upgrade my ovirt install and sofar the upgrade has been smooth.<br /> I'm running hosted-engine in Centos7.3 and my hosts are running Fedora24 now with ovirt-4.1<br /> 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:<br /> <br /> <span style="font-family: courier new,courier,monospace;">All running VMs will be temporarily reconfigured to use the previous cluster compatibility version and marked pending configuration change.</span><br /><span style="font-family: courier new,courier,monospace;"> 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.</span><br /><span style="font-family: courier new,courier,monospace;"> There are 1 running VM(s) affected by this change.</span><br /> <br /><span style="font-family: courier new,courier,monospace;"> Are you sure you want to change the Cluster Compatibility Version?</span><br /> <br /> Yes, I want to change version :-) so I click OK</div>
<div class="pre" style="margin: 0; padding: 0; font-family: monospace">I then get the following error message:</div>
