Hi,
we're successfully using Cinder as a Block Storage Provider for oVirt
with customized Cinder installation in a CentOS host according to
OpenStack docs. Now i wanted to try out running Cinder in Docker and
followed the instructions from
https://thenewstack.io/deploying-cinder-stand-alone-storage-service/
(customized for use with Ceph RBD).
This works to the point where i can setup an external provider and
consequently a storage domain in oVirt. I set up the provider without
authentication and testing this (by pressing "Test" button) works. When
i want to create disks i realize that oVirt doesn't recognize the
"Volume Type" definitions. In engine.log i see messages like
2018-10-03 12:04:46,990+02 ERROR
[org.ovirt.engine.core.bll.storage.disk.cinder.GetCinderVolumeTypesByStorageDomainIdQuery]
(default task-72) [06d4fbf7-0b3c-46b3-8166-148ee7f67a4c] Query
'GetCinderVolumeTypesByStorageDomainIdQuery' failed: null
2018-10-03 12:04:46,990+02 ERROR

(default task-72) [06d4fbf7-0b3c-46b3-8166-148ee7f67a4c] Exception:
java.lang.NullPointerException
I very much suspect that not using authentication (because of
"auth_strategy = noauth" in cinder.conf) is the culprit. Listing types
with cinder CLI from the engine host works (when using the appropriate
environment). Can some of the RH devs confirm this behaviour? Is this an
engine bug?
thanks
Matthias
