I'm trying to upgrade my cluster to 4.3. Currently its running 4.2.8.2-1.el7.
But the cluster compatibility version is 3.6.
I try to change that and it says I need to edit the VM.
https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks.html

says:
Important: An error message may warn that some virtual machines and templates are incorrectly configured. To fix this error, edit each virtual machine manually. The Edit Virtual Machine window provides additional validations and warnings that show what to correct. Sometimes the issue is automatically corrected and the virtual machine’s configuration just needs to be saved again. After editing each virtual machine, you will be able to change the cluster compatibility version.


I edit the VM and there are no errors or warnings. I see no way to change the cluster compatibility level on a VM.
How do I change the Custom Compatibility Version??
