I had an ovirt engine failure which corrupted my foreman/katello vm. My ovirt-engine is 4.3 and I was using foreman 3.0 with Katello 4.5. Once the ovirt-engine was repaired, still 4.3, I updated the foreman katello install to foreman 3.3 and Katello 4.5. I can connect from foreman to Ovirt as a compute resource but cannot add foreman to ovirt as an external provider.

I believe it's a certificate error vnd renamed the katello certs with a .bak suffix. I'm not sure ifit's a compatability issue but I researched it to death and so far came up empty. Any help would be appreciated. Thanks, Eric
