Disks don't have labels, partitions do. You don't see a partition in the KVM guest because the guest is trying to read a partition table from inside the partition that you're exporting.
Doh! I should have known that.
Instead, use one of the IDs in /dev/disk/by-id. You should see an ID that indicates the disk's model and serial number, which is usable for your purpose.
Most awesome - worked! Thanks a lot for the solution.
NB: I did see the disk IDs when I was trying to fix the problem myself and before I emailed the list. But, for some reason or another I didn't actually give it a go.
