Hm...
void virtio_instance_init_common(Object *proxydev,
DeviceState *vdev,
size_t vdevsize,
const char *vdevname)
{
object_initialize(vdev, vdevsize, vdevname);
object_property_add_child(proxydev, "virtio-backend", OBJECT(vdev), NULL);
object_unref(OBJECT(vdev));
qdev_alias_all_properties(vdev, proxydev);
}
and have the initializers call
virtio_instance_init_common(obj, DEVICE(&dev->vdev), sizeof(dev->vdev),
TYPE_WHATEVER);
?
