[ovirt-users] install of engine

Hi folks, I have installed the ovirt OS on 3 dl380's. It has been deployed with gluster and all is fine up to a point. When I try to install the engine it is trying to get out to the internet but unfortunately I am behind a proxy with strict rules, is there a way to point to a local copy of the engine using the GUI install or can I scp the iso over to the first node for local install, is there a particular partition where the iso should be stored. Any help appreciated, BR/David
