The qemu patchset you've mentioned doesn't seem to correspond entirely to what this libvirt patchset is adding. I was looking for the 'query-tdx-capabilities' QMP command which is used in patch 1 of the libvirt series, but the patchset you've mentioned doesn't add it at all. As noted libvirt requires that the features exposed by libvirt are accepted by upstream qemu before adding support for them, to prevent maintenance of diverged or non-existing features.
