We already declared that for qemu 1.3 and beyond, ALL command line behavior must ALSO be probe-able via QMP. I think Anthony had a trick for testing for existence of various command line options without needing to add a new query-strict-boot command, but I don't remember what that trick was. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
