Yes that would fix it for sure.  However if we require that admins have
to configure HWPs for rhevm in order to use heat then that will have to
be part of the steps for using it..  Not the end of the world but less
than ideal imo.

Could you not define defaults in the config that you can then edit?
This is what I am basically advocating.  That and they would all be the
same by default (same names, similar definitions accross providers).
