For what it's worth, I'm also in need of this feature. Some way to make a scsi tape available to a VM. On Fri, Apr 25, 2014 at 12:01 PM, Daniel Helgenberger <daniel.helgenberger@m-box.de> wrote:

Hello,
does anyone have an idea on how to accomplish this? In my particular setup, I need a FC tape drive passed though to the vm. Note, passing throuh FC - LUNs works flawlessly.
If I understood Virtio -SCSI correctly, this should be possible from libvirt's part.
I can be wrong but my understanding is that dm-mpio works on block layer thus it does not support multipath for tapes/cd-devices.
But I could be wrong, I got this info from an OpenBSD paper comparing SCSI multipath implementation.
j. 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.
