Hi,

We had a failure in test : 004_basic_sanity.verify_glance_import <http://jenkins.ovirt.org/job/ovirt-master_change-queue-tester/4829/testReport/%28root%29/004_basic_sanity/verify_glance_import/>

The issue is actually with engine loosing connection to host and assuming there was a failure. however, I could not find a failure in the vdsm which would be related to this issue.

Please note that there is a NPE in the engine log for trying to update the task status which I think is something that should be addressed.
