Ah, ovs-openflowd and ovs-vswitchd are not meant to be run together. ovs-openflowd is meant to be used as a drop-in replacement for the OpenFlow reference implementation. It provides the same functionality as the ofprotocol daemon (originally called secchan).

ovs-vswitchd is meant to be a more full-featured software-based switch that can be remotely managed by an OpenFlow controller. To have ovs- vswitchd connect to an OpenFlow controller, look at the "mgmt.controller" or "bridge.<bridge_name>.controller" keys in the ovs- vswitchd.conf man page. If you don't need OpenFlow reference code compatibility (and I don't imagine you do), I'd recommend using ovs- vswitchd.
