Using virtio-blk serial attributes add rules to extract drive serial numbers and
generate by-id links for the block device and partitions.
With these rules added, we now see the following symlinks in disk/by-id
% ls -al /dev/disk/by-id | grep vdb
lrwxrwxrwx. 1 root root 9 Jun 1 22:09 virtio-QM00001 -> ../../vda
lrwxrwxrwx. 1 root root 10 Jun 1 22:09 virtio-QM00001-part1 -> ../../vda1
