Hello there

I try to integrate OpenStack and OpenDaylight.

My environment are below.

• Openstack Mitaka and Opendaylight Beryllium-SR4
• Node 1 : Controller + Network
  (Process : openvswitch-switch,neutron-server,neutron-dhcp-agent,neutron-metadata-agent,neutron-l3-agent,etc)
• Node 2 : Compute ( Process : nova-compute , openvswitch-switch )
  • Node 3 : ODL ( Process : Only ODL )

I refer below sites.

https://wiki.opendaylight.org/view/Op...andOpenDaylight
http://sciencecloud-community.cs.tu.a...

http://superuser.openstack.org/articl...

Sum-up.

ODL : feature:install odl-ovsdb-openstack, odl-dlux-core, odl-dlux-all

Controller(Network) :

• ovs-vsctl set OpenvSwitch .... otherconfig={'local_ip'='10.0.0.1'}

• ovs-vsctl set-manager tcp:ODLIP:6640

• ovs-vsctl show ( work well)

• edit /etc/neutron/plugins/ml2/ml2_conf.ini

• remove neutron-openvswitch-agent

• reinstall DB

• Install the networking_odl python module

Compute Node :

• ovs-vsctl set OpenvSwitch .... otherconfig={'local_ip'='10.0.0.2'}

• ovs-vsctl set-manager tcp:ODLIP:6640

• remove neutron-openvswitch-agent

I have two problems.

1. VMs can't get IP address.

   There is no error log except when create subnet.

2. When create subnet, got below errors in neutron-server.log.

   But ODL seems work fine. (curl -u admin:admin http://localhost:8080/controller/nb/v... )

   eg. 'neutron subnet-create demo-net2 --name demo-subnet2 --gateway 192.168.201.1 192.168.201.0/24 '
