This takes me back. 9 years ago I was playing around with ZFS COW and OS X sparse bundle containers to host disks images for multiple "versions" (exploiting CoW) of the same VM image. I wrote up an article on what I was doing [1]. Never persevered though as it was a bit too fragile (at that time ZFS on OS X was not at all ready for prime time). Funny, but every so often I wonder what it might be like in a parallel world where Apple bought Sun instead of Oracle.
