I'm trying to rebuild our test images at:
https://hub.docker.com/u/ovirtorg/dashboard/

The fedora rawhide image fail with this error:

Problem: conflicting requests
  - nothing provides python2-blockdev >= 1.1 needed by python2-blivet1-1:1.20.4-3.fc28.noarch

Anyone has clue about this error? I guess this effects also vdsm.

David, do you know about this issue?
