First upgrade or reinstall your hosts with el7. oVirt 3.6+ does not provide packages for el6. el6 hosts will still work, but easiest to upgrade to el7 in 3.5. If you are using hosted-engine, you can follow [1]. Then upgrade to 3.6 using regular docs [2]. In 4.0, the engine is also el7 only. To upgrade, use engine-backup to backup, then reinstall the machine with el7, then restore. I do not think we have a special page for this, but you can follow the doc text of [3], which is also copied in the 4.0 release notes [4]. Please review [5] for more information about engine backup and restore. If you using hosted-engine, you can use the new upgrade tool to upgrade the engine vm using the engine appliance. Not sure that's properly documented either, see also [6]. Also note that this bug is for 4.0.2, to be released soon.

As always, if at all possible, better try first on a test system, especially if it's in production, and backup everything beforehand, including your VMs etc. Best regards, [1] https://www.ovirt.org/documentation/how-to/hosted-engine-host-OS-upgrade/ [2] http://www.ovirt.org/develop/release-management/releases/3.6/ [3] https://bugzilla.redhat.com/show_bug.cgi?id=1318580 [4] https://www.ovirt.org/release/4.0.0/ [5] http://www.ovirt.org/develop/release-management/features/engine/engine-ba...
