Opendaylight integration with Openstack using kolla-ansible

[Mansi Jain]

Hi, I was trying to integrate ODL with OpenStack (Queens) using Kolla-ansible. I did the following configuration in globals.yaml:

neutron_plugin_agent: "opendaylight"
 enable_opendaylight: "yes"
Also, I have to do the following modifications in kolla-ansible (stable/queens) code for my setup to be up: https://review.openstack.org/#/c/571441/

After successful deployment, ml2_conf.ini looks like this:

[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = opendaylight_v2
extension_drivers = port_security

[ml2_odl]
url = http://172.16.141.167:8088/controller/nb/v2/neutron
username = admin
password = gOI3BfzrDTNM2y7WFOkQavc6Z8EUe6BLhSBirgJN
port_binding_controller = pseudo-agentdb-binding

[ml2_type_vlan]
network_vlan_ranges =

[ml2_type_flat]
flat_networks = physnet1

[ml2_type_vxlan]
vni_ranges = 1:1000
vxlan_group = 239.1.1.1

[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

[agent]
tunnel_types = vxlan
l2_population = true
arp_responder = true

[ovs]
bridge_mappings = physnet1:br-ex
datapath_type = system
ovsdb_connection = tcp:127.0.0.1:6640
local_ip = 172.16.141.39

docker exec openvswitch_vsiwtchd ovs-vsctl show on network node:

Also, I tested ODL integration with OpenStack with the following command:

curl -u admin:gOI3BfzrDTNM2y7WFOkQavc6Z8EUe6BLhSBirgJN http://172.16.141.167:8088/controller/nb/v2/neutron/networks (http://172.16.141.167:8088/controller...)

Output:

}
But when I launched cirros instances on flat network, My VMs donot get IP from DHCP. Although, VMs on private network are working fine.

Is flat network supported in ODL(Carbon)?

Please help regarding this issue.
