Hello all,

I thought I would give quantum a shot and I've got a 50-60% working configuration, but having trouble understanding where to go from here as the docs are pretty sparse.

Ubuntu 12.04.1 + "ubuntu cloud archive" folsom repo

node A: nova-api, nova-scheduler, quantum-server, quantum-plugin-openvswitch
node B: nova-compute, nova-api-metadata, quantum-dhcp-agent, quantum-plugin-openvswitch-agent
node C: nova-compute,
nova-api-metadata, quantum-dhcp-agent, quantum-plugin-openvswitch-agent

configured as follows:

quantum.conf:
...
core_plugin = quantum.plugins.openvswitch.ovs_quantum_plugin.OVSQuantumPluginV2
...

ovs_quantum_plugin.ini:
...
tenant_network_type=vlan
network_vlan_ranges = default:2000:3999
integration_bridge = br-int
bridge_mappings = default:br-eth3
...

node B,C `ovs-vstl list-br`:
br-eth3
br-int

node B,C `ovs-vsctl list-ports br-int`:
int-br-eth3 (created by quantum?)

node B,C `ovs-vsctl list-ports br-eth3`:
eth3 (added by me)
phy-br-eth3 (created by quantum?)

eth3 is a NIC which is connected to a switchport accepting VLAN 2000:3999. It has no IP assigned currently.

When I start the 12.04 ubuntu "cloud-image" in the dashboard, it successfully boots and obtains an IP address as seen in the console output:
cloud-init-nonet waiting 120 seconds for a network device.

ci-info: lo    : 1 127.0.0.1       255.0.0.0       .
ci-info: eth0  : 1 192.168.253.5   255.255.255.0   fa:16:3e:80:33:71
ci-info: route-0: 0.0.0.0         192.168.253.1   0.0.0.0         eth0   UG
ci-info: route-1: 192.168.253.0   0.0.0.0         255.255.255.0   eth0   U

However, immediately after that output I see this

2012-11-07 11:27:29,598 - util.py[WARNING]: 'http://169.254.169.254/2009-04-04/meta-data/instance-id' failed [3/120s]: url error [[Errno 113] No route to host]

which runs until it times out.

In older versions of OpenStack, when I ran 'iptables-save | grep 169.254.169.254' on a metadata server I was used to seeing a rule show up which translated that 169 address to the variable assigned by metadata_host in nova.conf, but I note that rule doesn't show up in this version of nova? I added the old rule in (to see what would happen) but the result was the same, still no route to host.

What steps do I need to take here to allow my instance to retrieve its metadata? Is my quantum misconfigured somehow? Perhaps I need to go back and reconfigure my switch port (for example, there is no real 192.168.253.1 gw, but does there need to be for the instance to simply fetch metdata)? After that, what steps do I need to take to get the VM connected to the rest of the world? Is the quantum-l3-agent the only real choice right now?

Thx.
