Testing error on my part. Was using an adaptation of an old patch set.
With Brijesh's SEV-SNP support adapted to this version on top of
SEV-SNP guest patch series v12, I have no trouble with passing our
memtouch test.

Ah Guest unaccepted memory validate patch was missing. Good to know itworked for you. Thank you for sharing the result.


Best regards,
Pankaj
