    <p>I had a similar problem, in my case this was related to
      multipath, it was not masking the LUNs correctly, it was seeing it
      multiple times (one per path), and I could not select the LUNs in
      the oVirt interface.</p>
    <p>Once I configured multipath correctly, everything worked like a
