I can confirm that this series works for the SEV-SNP guest. I was able to hook the SEV-SNP page validation vmgexit (similar to the TDX patch#7) and have verified that the guest kernel successfully accepted all the memory regions marked unaccepted by the EFI boot loader. Not a big deal, but can I ask you to include me in Cc on the future series; I should be able to do more testing on SNP hardware and provide my Test-by tag.
