Description of problem:
Hi All,
I've upgraded my infrastructure - configured with separate hosts for Engine, DWH and Reports - from oVirt 3.6 to 4.
Clearly first I've upgraded the Engine (without particular difficulties) then I've started the upgrade of DWH host. After the upgrade with yum I've launched engine-setup to update DB, etc., but the result was a laconic
"***L:ERROR Internal error: No module named engine"
Maybe that engine-setup expect to find installed also oVirt engine on the host where it get executed?
Thanks for your support,
Stefano.

1.Upgrade DWH from oVirt 3.6 to 4
2.launch engine-setup
3. I've also tried with a fresh installation of DWH with the same result

Can you please attach output of:
OTOPI_DEBUG=1 engine-setup

No, and if it does, it should not.
Thanks.

Ouch. That's a bug.
A plugin in ovirt-engine-common must not import from engine, which does not exist on other machines.
Thanks for the report!
