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.
