[ovirt-users] Re: OpenStack Block Storage Provider without authentication doesn't work

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?

So - regardless if i wanted to actually use it that way - I consider this a bug in Cinder integration in oVirt.
