you can run multiple agents per node, assuming you are running with namespaces enabled.

digitalwonk is still having a problem: Thanks for the response Yong.

The l3 log currently report the following error message repeatedly:

2013-03-04 14:14:56 ERROR [quantum.agent.l3_agent] Error running l3_nat daemon_loop Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/quantum/agent/l3_agent.py", line 171, in daemon_loop self.do_single_loop() File "/usr/lib/python2.7/dist-packages/quantum/agent/l3_agent.py", line 202, in do_single_loop target_ex_net_id = self._fetch_external_net_id() File "/usr/lib/python2.7/dist-packages/quantum/agent/l3_agent.py", line 185, in _fetch_external_net_id raise Exception("must configure 'gateway_external_network_id' if " Exception: must configure 'gateway_external_network_id' if Quantum has more than one external network.

So, if I have two separate external subnets, is there no way to have both of them being used on the same network node? Or would I need to somehow setup a separate quantum network node?

If I have to specify only one gateway_external_network_id, then why would anyone have more than external networks?

Thank you, Edwin
