  Well, there are some corner cases where you can't easily get the hosts
  raw keys.  In that case qemu tries to translate the keysyms back to
  raw keycodes using the maps in /usr/share/qemu/keymaps.  See also qemu
  manpage, "-k" switch.

But, yes, using linux keycodes as wire encoding IMHO is the way to go.

cheers,
  Gerd
