We already do this in qdev_init_nofail:
if (!OBJECT(dev)->parent) {
static int unattached_count = 0;
gchar *name = g_strdup_printf("device[%d]", unattached_count++);
object_property_add_child(container_get(qdev_get_machine(),
"/unattached"),
name, OBJECT(dev), NULL);
g_free(name);
}
Probably we should move this piece to a function qdev_attach, so that
you can call it before object_property_set_link.
Alternatively, we could make object_property_set_link bypass the
canonical paths and write the pointer directly, but I think this would
be bad.
