*** Bug 1299236 has been marked as a duplicate of this bug. ***
Note that RHEV 3.5.z should support EL6, which has a considerably older libvirt version. Not sure if this changes the solution, but at the very least it should be verified on both platforms.
Verified with ============= rhevm-3.5.7-0.1.el6ev.noarch vdsm-4.16.33-1.el7ev libvirt-1.2.8-16.el7_1.5 Steps to Reproduce: =================== 1. Assign a Direct Lun to a VM with interface "Virtio-SCSI" and "Enable SCSI Pass-Through". Works fine.
