I can't say for sure if Xen domu's can use zvols as a backing storage,
as I for the moment have stopped using Xen with NetBSD - although I
think it should work. I can say that qemu-nvmm works rather well for
me with zvols, though, which is what I now use as a virtualisation
solution under -current. I realise the parallel is not quite right, of
course.
