[Openstack] Neutron (Havana) configuration on Ubuntu

Hi Ross,
You also have to assign the router you created an interface on the admin-net.1
If everything is setup correctly you can then run "neutron router-list" to see the ID of the router you created, and then "neutron router-port-list ROUTER_ID" and you should see that your router has two interfaces: one on the admin-net.1 subnet with IP 10.0.1.1/24 and another one on the admin-net.float subnet.
There are three steps involved in setting up a private router: create the router, add an interface to the private network and then set its external gateway and the process is documented here: http://docs.openstack.org/havana/install-guide/install/apt/content/demo_per_tenant_router_network_config.html (Step 5d)
I hope this helps.
George

Subject: [Openstack] Neutron (Havana) configuration on Ubuntu
If this issue has already been discussed, please excuse.
I'm somewhat confused about neutron configuration and tenancy. Correct me if I'm wrong.
First, I've create a private network under the 'admin' tenant named 'admin-net'. I've associated a subnet named admin-net.1 with the admin-net with a CIDR of 10.0.1.0/24.
Next, I created a network with router:external set to True associated with our campus network named 'campus-net'. This network was created under the 'service' tenant'. I also create a router named 'campus-gw' under the 'service' tenant and set it's gateway to be the 'campus-net' network.
Finally, I create a floating address pool under the 'admin' tenant named 'admin-net.float', and add it as an interface to the 'campus-gw' router. I also create a default security group under the 'admin' tenant to allow SSH and ICMP access.
When I boot an image, as a member of the admin tenant, the instance is correctly assigned an IP address from the admin tenant's private network. I next allocate (nova floating-ip-create admin-net.float) a floating IP address and associated it my running instance.
However, I'm unable to ping the running instance, and I see no indication of the end of the tunnel being established on the network/controller node.
I'm not that well versed with network namespaces nor the openvswitch commands.
2 questions. Does my overall configuration sound correct? And how best to diagnose what's going on here? Any pointers would be helpful. Additional details can be provided as needed. Thanks loads in advance.
Regards,
