Legacy is not going to be a 1st class citizen and that was a concious decision the TC made. In particular we know straight away that there is no way to make them safely work while preserving assumptions confidential computing guests make (which I guess is what you mean here). The whole point of isolating legacy mess in the special commands was so we don't try to support them going forward, don't try to add new features for legacy interfaces please. -- MST This publicly archived list offers a means to provide input to the OASIS Virtual I/O Device (VIRTIO) TC.
