So ICO 2.4 requires the Deployment Server machine to have interface br0 defined as a bridge connected to eth0. However, ICO 184.108.40.206 does NOT want br0, but wants eth0. I had already created br0 using the virsh command, so I had to look up how to remove it, and it's very simple once you find it:
virsh iface-unbridge br0
and that's it. It puts all of the configuration back on eth0 and you're in business.
