Hi, We are trying to install ovs-dpdk in kolla(stable/pike) .we are following all the steps given in official kolla document.

https://docs.openstack.org/kolla-ansi...

After deployment we faced an issue of opensvswitch container in restarting mode.This was resolved with changing ovsdpdk-db config.json ip to loopback(127.0.0.1)

Now If we are trying to launch vm it fails neutron-server logs

 ERROR neutron.plugins.ml2.managers [req-f00b1dbe-b848-4da7-b9bf-88d81b6d2eb1 6242fbbd4d0a4232a7c64b8716d85b51 f3a5ea8fbd174034ac858d6cfc64bff3 - default default] Failed to bind port 41781393-5432-44fc-9a4b-afe9e01c892e on host controller201652 for vnic_type normal using segments [{'network_id': '69f3765b-4d27-4d84-87d3-5c442d9a6b0a', 'segmentation_id': None, 'physical_network': u'physnet1', 'id': 'aeb916b9-018b-45d4-b9fb-8170dd288c3d', 'network_type': u'flat'}]

Issue might be with interface creation for Vm.

PS: if we set vif_plugging_is_fatal: false we are able to launch vm but then vm interface does not get an ip.
