Those, and query-qmp-schema. If the change includes the addition of something new in the .json files describing QMP, then query-qmp-schema will let libvirt probe whether the version of qemu it it talking to has that new field or not (presumably, in this case it would be a new optional bool member to select the mode when creating a job, as well as a new command visible through query-commands to change the mode of a running job). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
