With unknown good reasons, the attribute "bus" of scsi device address is always set to 0, same for attribute "target". (See virDomainDiskDefAssignAddress). Though we might need to change the algorithm to honor "bus" and "target" too, that's a different issue. The address generator for scsi host device in this patch just follows the unknown good reasons, only considering the "controller" and "unit". It walks through all scsi controllers and their units, to see if the address $controller:0:0:$unit can be used (if not used by any disk or scsi host device yet), if found one, it sits on it, otherwise, it creates a new controller (actually the controller is implicitly created by someone else), and sits on $new_controller:0:0:0 instead.
