<p class="MsoNormal" style="margin-bottom:12.0pt">Looking at this again I would like the webui install process to add the repo too :-)<br>
If engine-setup is up to date it could know the location of the ovirt-repo.rpm and install it automatically. There is probably a very good reason why it doesn't do this since I can't imagine I'm the first one to think about this.<br>
