This example mentions 'convert-in-place=on', but I don't see that property implemented in this series. Is the example a mistake or is this from a further follow-on series yet to come ? Also as a more general conceptual question, in there going to be any equiv to SNP's "hostdata" or TDX's "mr-config-id", that will let the guest owner pass in some bytes of data that get included in the measurement ? Trustee has mention of "CCA_REALM_PERSONALIZATION_VALUE" for Arm. Would that become a property of 'rme-guest' in future work ?
