The vmstate's pre_save and post_load functions can dispatch to a method in the subclass. Again, i8259 does exactly what you want: static void pic_dispatch_pre_save(void *opaque) { PICCommonState *s = opaque; PICCommonClass *info = PIC_COMMON_GET_CLASS(s); if (info->pre_save) { info->pre_save(s); } } Paolo
