Hi, Please continue this discussion on ML that anyone can see it :) What agents do You exactly see in “neutron agent-list” command then? What You have set as “host” value in linuxbridge agent’s config on different nodes? Can You enable DEBUG log and send it also?

Hi,

What exactly do You mean by saying “the compute node is not found”? Is neutron-linuxbridge-agent from compute node not visible in “neutron agent-list” result or it is visible but down? Or something else? Also, please send logs as plain text instead of screenshots - it will be much easier to read :)

Hello, I am a newcomer to openstack. I have a problem. When I enter the command "openstack network agent list" on the controller node, the compute node is not found. Below are the output of the compute node's and controller node’s linuxbridge-agent.log.look forward to your reply.
