I have oVirt 3.6 running on CentOS 7 (one engine, two hosts). Upgrading to 4.0 seems to
require a fresh, bare install of CentOS7 on the engine machine - is this a correct reading
of the upgrade guide? It seems bizarre to me I have to wipe a perfectly fine running
CentOS7 machine to do this - that seems so Microsoft.
Say it isn't so...

Actually, the current version only supports ovirt 4.1 onwards.
Thanks

The upgrade guide says you must go 3.6 -> 4.0 -> 4.1 etc
https://www.ovirt.org/documentation/upgrade-guide/chap-Upgrading_from_3.6...
I just want to know if I really, really have to bare metal install of CentOS all over?
That seems crazy in a Linux world.

This is a CentOS question, not an oVirt one.
Last time we tried this, in-place upgrade didn't work well, so it's not
documented nor tested. But if you manage to make it work, upgrading the
oVirt engine inside the machine might work just as a normal upgrade (add
repos, update setup packages, engine-setup, update the rest).
One important issue is the PostgreSQL database. If you manage to upgrade
the OS in-place, this upgrade should hopefully upgrade your database as
well. But just in case, manually verify that it did.
Bottom line: It's safer and simpler to reinstall, unless you have some
concrete reasons (custom stuff etc.) that make it worthwhile for you
to try in-place upgrade.
