I added the setup logs i found at: http://www.klaros-testmanagement.com/files/ovirt/ovirt-setup-logs.tar.gz Again, please let me know once I can remove them.

We almost never skipped a release.

There was indeed one glitch during updates which was connected to the Postgres version in use: The initial install was (accidentally) done under Postgres 9.4 which happened to be present on the machine at that point of time. oVirt 4.0 was allowing this way back then. I think in 4.1 Postgres 9.2 has been enforced, so there had been workarounds to allow updates under 9.4. This got resolved with the migration to 4.2 which brought the Postgres 9.5 installation (if I recall that correctly). Other than that I have no idea which might have introduced this.

If you find something in the logs you need more information on, please let me know.
