Based on the previous comment by Jiewen it seems TDX folks want to have a separate metadata for flexibility. In the v9, I am creating metadata just for the SEV with a different GUID. Basically same as version 8 but now the number of descriptors will be smaller (since we focus on SEV-SNP). thanks > If so, then the section types need some more structure.
