[ovirt-users] Re: Is enabling Epel repo will break the installation?

oVirt developpers are not big fan of epel anyway. So don't expect this situation to change soon. To be sure that epel don't interfere in any way with oVirt epel, rather than excluding collected, I changed the priority of oVirt's epel: in /etc/yum.repos.d/ovirt-4.2-dependencies.repo [ovirt-4.2-epel] ... priority=10 The default priority is 99, so whatever package ovirt choose to add in it, it will win other epel.
