Zachary, The version lock is used by oVirt devs to prevent the system to update too far ahead of the oVirt level. Don't remove that next time. You should access the engine only by https://FQDN .IP should not be used. If you have some kind of snapshot (for example gluster) - you can consider reverting. Even consider restore from backup. I'm pretty sure that almost every failiure is recorded somewhere there ... (I am still new to advise location).
