If you look the scripts in /var/lib/one/remotes/vnm/ovswitch/, you see that
ovs-vsctl and ovs-ofctl are used to configure the bridge when a VM is
attached. That is the openvswitch driver of opennebula.
What I want to say is that probably you cannot connect the bridge to the
controller, because it is already controlled and managed directly by these
scripts.
I think this question should be written on the developer mailing list,
because I'm not sure if I'm right, but I think that for you there is the
need to create a "floodlight driver", to control the bridge instead of use
the openvswitch driver.
I hope this time I was clear and right :D

The connection between openvswitch and floodlight controller is on 
different ethernet port (eth1).

This is only a supposition I made, because now I can't perform any test.
Probably is better if you wait an answer from a more expert user/developer.

Physical switches are IBM EN4093R (10Gb) and connected with openflow
to the same floodlight controller. openvswitch is of 1.4.2 in Debian
7.4.

# ovs-vsctl show
8505aff4-42e3-48c2-9173-__fa0fbe5caeb3
 Bridge "br0"
 Controller "tcp:192.168.42.68:6633 "
 is_connected: true
 Port "eth0"
 Interface "eth0"

br0 have IP, eth0 have no IP.

With floodlight in forwarding mode I have connectivity between
hypervisor nodes (with IP of br0) and to storage nodes (for iSCSI),
but VMs on different nodes doesn't see each other.

 Hi,

 I'm trying to use openflow controller + openvswitch + KVM +
hardware
 switch with openflow support.

 Could provide some advice, because I cannot get it running
by using
 opennebula default config + kvm + openvswitch (ping works
with VMs
 in the same node and fails to VMs in another nodes).

I think you cannot connect the openvswitch bridge to the openflow
controller, because the network driver of opennebula performs some
