Because libvirt already allows users to pass in integers instead of symbolic names. Providing integer support in QMP would let the path be passthrough, instead of libvirt doing a reverse lookup to convert integer to symbol just to call QMP for qemu to do a lookup from symbol back to integer. > > I don't quite understand why anyone would want to use hex actually... > You would have to convert from whatever symbolic code you're using to > QEMU's hex value so why not just stay in symbolic representation. Staying just symbolic is fine - remember, I already stated that libvirt already has a lookup table to convert between several different keycode sets already, and Dan Berrange has already proposed sharing that table with qemu. And settling on symbolic as the only interface, even if it is less efficient than integer passthrough, is at least easier to maintain. -- Eric Blake ebl...@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
