[ovirt-users] no network interface

Hi. I had ovirt running with a VM but it suddenly broke. I wiped it all and did a reinstall but now I am not able to connect my host to the network. the host is always saying status='unassigned'. in the network page where I would drag and drop a connection, there is no interface to connect to. its this page https://ovirt.org/images/wiki/SetupNetworksNew.png?1478101462 but there is nothing in the interfaces column on the left Can anyone point me in the right direction to fix this? Thanks I have only one machine with the engine and host on it.
