This can also be done this way:

static Property ide_properties[] = {
    DEFINE_PROP_UINT32("unit", IDEDrive, dev.unit, -1),
    [ ... ]
    DEFINE_PROP_END_OF_LIST(),
};

           .qdev.props   = ide_properties,

Works only as long as all devices have exactly the same set (i.e. for 
scsi it wouldn't work as not all devices have the "removable" property).

I tend to like this more than the #define.  YMMV, matter of taste.

cheers,
