I'm deploying openstack icehouse version with three-node architecture (controller node, network node, and compute node1) on Debian wheezy.I use ml2 plugin and gre type driver.

Now, I notice some exceptions information in both the ovs-agent.log of network node and compute node.

From http://openstack.redhat.com/forum/dis... , & https://lists.launchpad.net/openstack... . the first link prompts to add tcp connection in iptables, but I disable firewall rules. So this does not work.

Also, I refer as to source code of neutron ( https://github.com/openstack/neutron/... ), but have no idea.

I just want to understand why this information exists and then eliminate the information. Thanks in advance.

Hi, dwyaneini. It's my understanding -- I read about it in the last two weeks or so -- that when the agents first boot up, they are out of sync. And that's normal behaviour. Then they do synchronize, but no message is written back in the logs, AFAIK. Regrettably, I don't remember whether I read it here on Ask OpenStack, on a mailing list, or elsewhere.

Thanks for your response, gkeller2. Through reading the source code of this part, I agree with you. When the agent first boots up, it must execute the code "Agent out of sync with plugin!", then set the state to "false", and do synchronize. Firstly, I make a mistake that misunderstand this info show up every time
