I have setup a multi-node openstack environment with a controller, network and computer node per instructions for multi-node deploy example in (

Most forum answers for this issue, assume a single (controller+network) node The commands like "ip netns" or "ovs-vsctl" do not make sense in a controller node; while the openvswitch, L3 and DHCP agents are all setup in the network node. I am not sure how the controller and network node work with each other.

In controller node, "ip netns" returns nothing. In network node, it returns "Object "netns" is unknown, try "ip help"."

Following are the output of "ovs-vsctl show" in controller and network nodes:

ovs-vsctl show

06af5443-1ec0-439a-ab74-c91d891f4869 ovs_version: "1.11.0"

ovs-vsctl show

6020cca2-9845-4e2b-bc72-6ec9d7a48d10 Bridge br-int Port br-int Interface br-int type: internal Bridge br-ex Port "em3" Interface "em3" Port br-ex Interface br-ex type: internal ovs_version: "1.11.0"

Any help is much appreciated.

Thanks Anil. I updated iproute in the network node and now "ip netns" returns nothing in the network node as well. I suspect this is the major problem with my setup. The namespaces should show up.

I have enabled "use_namespaces = True" in the /etc/neutron/l3_agent.ini config file of the network node.

Is there any other config file snippet you would like me to share?
