I'm still not sure how I achieve by use case of the parent class defining the following properties: static Property vud_properties[] = { DEFINE_PROP_CHR("chardev", VHostUserDevice, chardev), DEFINE_PROP_UINT16("id", VHostUserDevice, id, 0), DEFINE_PROP_UINT32("num_vqs", VHostUserDevice, num_vqs, 1), DEFINE_PROP_END_OF_LIST(), }; But for the specialisation of the class I want the id to default to the actual device id, e.g.: static Property vu_rng_properties[] = { DEFINE_PROP_UINT16("id", VHostUserDevice, id, VIRTIO_ID_RNG), DEFINE_PROP_UINT32("num_vqs", VHostUserDevice, num_vqs, 1), DEFINE_PROP_END_OF_LIST(), }; And so far the API for doing that isn't super clear.
