Update - the fix for ovirt-engine that Liran previously mentioned on this thread was merged.
@Michaal R about your question below, I don't think there is a workflow that fits all - it depends on the issue.
Even in this thread - the issue on the VDSM side required your help in validating the fix on your environment, while the fix in ovirt-engine could be validated by us with the VM specification you provided (we added a unit test with the specification of your VM btw).
As I see it, this thread went well - you provided us with information that enabled us to identify the issues and validate their fixes, which is great
