I think it is good practice to specify the default value:
> +my %scsiblock_fmt = (
> +scsiblock => {
> + type => 'boolean',
> + description => "whether to use scsi-block for full passthrough of host
> block
> device\n\nWARNING: can lead to I/O errors in combination with low memory or
since it can cause I/O errors and data corruption in low
memory or highly fragmented memory situations since Qemu 2.7
use scsi-hd by default instead
