Hi Matthias,
Thanks for the detailed information!
It looks like you've found a bug. A NullPointerException should never occur.
Can you please file a BZ and attach all the relevant logs so we can
understand the root cause for it?
Thanks,
Idan

I switched one of the existing, working Cinder hosts (no Docker
involved) to "auth_strategy = noauth" and the problem (and error
message
in engine.log) with querying volume types is the same. So - regardless
if i wanted to actually use it that way - I consider this a bug in
Cinder integration in oVirt.
