[ovirt-users] Hosted Engine install via cockpit - proxy issue

I am installing oVirt in a closed environment where internet access is controlled by proxies. This works until the hosted engine install via cockpit where it fails to complete as it appears to require internet access to the repository. The only workaround I have found is to ssh onto the engine ‘mid install’ and add the proxy address to /etc/dnf/dnf.conf. After doing this the install is successful. Am I missing something or does this type of install require unfettered internet access?
