Example 25 with VolumeDataStoreVO

    /*
        When we download volume then we create entry in volume_store_ref table.
        We mark the volume entry to ready state once download_url gets generated.
        When we migrate that volume, then again one more entry is created with same volume id.
        Its state is marked as allocated. Later we try to list only one dataobject in datastore
        for state transition during volume migration. If the listed volume's state is allocated
        then migration passes otherwise it fails.

         Below fix will remove the randomness and give priority to volume entry which is made for
         migration (download_url/extracturl will be null in case of migration). Giving priority to
         download volume case is not needed as there will be only one entry in that case so no randomness.
