The SEV FW >= 0.23 added a new command that can be used to query the attestation report containing the SHA-256 digest of the guest memory and VMSA encrypted with the LAUNCH_UPDATE and sign it with the PEK. Note, we already have a command (LAUNCH_MEASURE) that can be used to query the SHA-256 digest of the guest memory encrypted through the LAUNCH_UPDATE. The main difference between previous and this command is that the report is signed with the PEK and unlike the LAUNCH_MEASURE command the ATTESATION_REPORT command can be called while the guest is running. Add a QMP interface "query-sev-attestation-report" that can be used to get the report encoded in base64.
