We could deprecate the expensive fields on query-cpus, and move them to a more expensive query-cpu-state command. I believe most users of query-cpus are only interested in qom_path, thread_id, and topology info. Markus, Eric: from the QAPI point of view, is it OK to remove fields between QEMU versions, as long as we follow our deprecation policy? -- Eduardo -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
