[one-users] opennebula + KVM + openvswitch + openflow controller

[Marco Fanti]

I think you cannot connect the openvswitch bridge to the openflow
controller, because the network driver of opennebula performs some
operations with ovs-vsctl and ovs-ofctl, so when you connect the controller
to the bridge, you disupt the correct working of the openvswitch opennebula
driver.

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.
