The upgrade process went fine. The upgrade script never showed any errors.

I backed up the installation but then I ran in-place upgrade. I was told
on the irc I don't need to restore from backups when I'm already on
CentOS 7. Actually failing to restore from backup brought me to the IRC
in the first place.
I'm on CentOS Linux release 7.2.1511 (Core)
Upgrading I followed exactly the same doc you pointed to below.
Except when updating to 4.1 failed, I uninstalled everything that had to
do with ovirt and installed the 4.0 release.

Because of that doc I installed 4.1 instead of the stable 4.0 ...

Out of curiousity, where did you see that 3.6 to 4.0 update failed?

I'll try from scratch again, uninstalling everything, installing 3.6,
restoring backups and upgrading to 4.0
I don't want to be a party popper but to be honest you need a testing
engineer. The upgrade process is way too fragile and breaks too easily...
