I added the entire drive as a second storage disk to the KVM. I used the disk's label (/dev/disk/by-label/backups) so that I wouldn't have to worry about the device name changing down the road. When I booted up the KVM and listed the disks, I only saw "/dev/vdb". I was also expecting to see "/dev/vdb1".
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.
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.
