[Users] how do you manually add ovirtmgmt network to a node/host

Trying to install ovirt node on an already existing kvm host. Used the "New" wizard from the engine. Things seemed to go ok ish until it got to the point where it wanted to install networking. No real errors, but has "One of the Logical Networks defined for this Cluster is Unreachable by the Host." error sitting on it. I tried dragging that network onto one of the interfaces of my host, which already has an IP address, as that's how I ssh to it, and it then took down the interface and tried to dhcp an ip for it which failed after a while, and resulted in udev stuck in an infinite loop taking down and bringing up said interface. Not really sure what's going on or what it's trying to accomplish. I set the ovrtmgmt network to have the same vlan id as the ethernet device i dragged it onto. thanks for any help.
