Hi all,

I am running openstack stein in centos 7 in a two node format(controller,compute) and have it integrated with odl 9.3. When I am launching a virtual machine I am getting an error and the failed to bind port physical_network none in neutron logs.

 Failed to bind port a2ecbd29-a77a-490e-88b6-53c06bb2ab7a on host compute.lab.local for vnic_type normal using segments [{'network_id': '35713b74-6bec-4f0b-92aa-d3ea84fcda9d', 'segmentation_id': 54, 'physical_network': None, 'id': '6bdf6d48-9a1e-4ff5-9a1d-de1fc8c36b74', 'network_type': u'vxlan'}]

Any idea why?
