[ovirt-users] Hosted Engine 4.5 Deployment Issues

Hi There, Apologies in advanced, I'm sure this has been asked before, but I struggle to find anything in the documentation. I'm currently in the process of deploying my first oVirt instance, and having a issue when the Hosted Engine is trying to Install the Hosted Engine Package. Error from the logs attached. My Environment is behind a proxy, which blocks access to any domain containing the word mirror, so I understand why the error would be thrown. Is there any way to update the repos so I can point them to alternative sources? I have a working local mirror in my environment which does contain all the packages required for oVirt. Kind Regards, Nathan
