Tested on qemu-kvm-rhev-2.12.0-29.el7, not hit this issue, qemu will prompt "conflicts..." or "in use..." as below. So set status to VERIFIED when it is ON_QA.
# sh bug_1673402_with_blockdev.sh
QEMU 2.12.0 monitor - type 'help' for more information
(qemu) qemu-kvm: -device scsi-hd,id=data1,drive=drive_image1: Conflicts with use by image1 as 'root', which does not allow 'write' on drive_image1
# sh bug_1673402_with_drive.sh
QEMU 2.12.0 monitor - type 'help' for more information
(qemu) qemu-kvm: -device scsi-hd,id=data1,drive=drive_image1: Drive 'drive_image1' is already in use by another device
