OpenStack Block Storage Provider without authentication doesn't work
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 [org.ovirt.engine.core.bll.storage.disk.cinder.GetCinderVolumeTypesByStorageDomainIdQuery] (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

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. Matthias
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?
