Description of problem:

While deploying ovirt-hosted-engine, administrator is asked about the type of VM installation (cdrom, disk, pxe). If cdrom is selected, and information regarding cd/dvd device node provided, during VM startup deployment will fail, without valid information regarding the cause of failure. Log however contains the following:
