The fix for bug 1731868 left a interim change in ds-identify referencing an undeclared variable.
That code path would be hit if you attached an ISO filesystem to a device other than a cdrom. For example:
qemu-system-x86_64 -enable-kvm \ -device virtio-net-pci,netdev=net00 \ -netdev type=user,id=net00 \ -drive file=disk.img,id=disk00,if=none,format=qcow2,index=0 \ -device virtio-blk,drive=disk00,serial=disk.img \ -drive file=my-seed.img,id=disk01,if=none,format=raw,index=1 \ -device virtio-blk,drive=disk01,serial=my-seed.img \ -m 768 -nographic
It would work fine if you attached the iso filesystem as a cdrom. (-cdrom my-seed.img)
