No, I think so too - it does not support tape drive as such (but I could set up a tape library as a LUN to use it with LTFS for instance)
The point being is another. VirtIO SCSI should be able to pass through any scsi device; like tape drives end enclosures. I know this works in Proxmox: http://pve.proxmox.com/wiki/Tape_Drives Does it work in oVirt, too? In the GUI I only see block LUNs from DM. -- Daniel Helgenberger m box bewegtbild GmbH P: +49/30/2408781-22 F: +49/30/2408781-10 ACKERSTR. 19 D-10115 BERLIN www.m-box.de www.monkeymen.tv Geschäftsführer: Martin Retschitzegger / Michaela Göllner Handeslregister: Amtsgericht Charlottenburg / HRB 112767
