When a device model's I/O operation fails, we execute the error
action. This lets layers above QEMU implement thin provisioning, or
attempt to correct errors before they reach the guest. But when the
I/O operation fails because its invalid, reporting the error to the
guest is the only sensible action.
This short series does exactly that for virtio-blk. I intend to do
the same for IDE and SCSI.
Actually SCSI already does it (see check_lba_range in
hw/scsi/scsi-disk.c). Thanks for thinking about it though!
