TODO
Set default value of @var{driver}'s property @var{prop} to @var{value}, e.g.:
@example
qemu -global ide-drive.physical_block_size=4096 -drive file=file,if=ide,index=0,media=disk
@end example
In particular, you can use this to set driver properties for devices which are
created automatically by the machine model. To create a device which is not
created automatically and set properties on it, use -@option{device}.
