We already have a werror option in -drive that controls the action to be taken when write accesses to the image fail. A corresponding option for reads is still missing and is added by this patch series.
The option is implemented on IDE and virtio-blk. I have left out SCSI for now to avoid conflicts with kraxel's major restructuring work.
