If you mean this: "See GHCB specification for further detail on how to parse the certificate blob." that ain't even scratching the surface. You need to explain that magic "certs_len == 0" condition in that textm how it is handled and what that causes the HV to do. You need to realize that because it is clear to you, it ain't that clear to others. -- Regards/Gruss, Boris. SUSE Software Solutions Germany GmbH, GF: Ivo Totev, HRB 36809, AG Nürnberg
