  ah right I tested the rc3 tarball !

  The tests which fails are the ones where there is a <cpu match>
and a model is specified. Maybe something changed there, because
tests/qemuxml2argvdata/qemu.sh used emulate the faked cpu on boxes
where qemu isn't available but it seems to not be called any more
with "-cpu ?" and hence can't fake the supported CPU on those boxes.
