AFAIK, it's possible with sheepdog,rbd,nexenta and files of course. (I Think that lvm is possible too)


Maybe One thing not possible  with current disk naming it's sharing a disk between 2 guests. (with ocfs2 fs cluster in guests by example)

What about just renaming disks if you want to move disk from vm A to vm 
B? Not sure if all storage backends support this but at least some do.
