Tim, if you can't get Python 2.7 from SCL working acceptably,
what would be your fallback approach ?  Would you try to patch
Nova to work on Python 2.6 again, or would you simply delay
updating Nova until you have v7 hosts to run on ?

Likewise if we were to decide to drop support for libvrt in
v6 from Nova, how would you imagine dealing with that ? Would
you just re-add the compat code we removed from Nova to make
it work with old libvirt again ?
