I have a problem to start the neutron-plugin-openvswitch-agent service in the "network node". when i run :

service neutron-plugin-openvswitch-agent restart

the output is :

stop: Unknown instance :
neutron-plugin-openvswitch-agent start/running, process 21277

But, if i run :

service neutron-plugin-openvswitch-agent status

the output is :

neutron-plugin-openvswitch-agent stop/waiting

Someone help me please. Thanks

There can be many reasons for this. Share the logs of the service "openvswitch-agent.log".

I also has the same problem today. And I totally solve the problem. I will leave here my solution as a reference.

The first very thing to aware of is that we should not leave any space for each line in a configure file of openstack.

For example, the conig. file: ml2_conf.ini when installing the openvswitch on network and compute1 node: if we just uncomment a line like this:

   tenant_network_types = gre

Then we will end up with a problem. And we will find that when we restart a service, soonly we will find it stop after few seconds.

So we should not only uncomment a line, but also remove the space like this:


For openvswitch problem like this thread, there's an additional problem that we may found in the log file:/var/log/neutron/openvswitch-agent.log

It is a problem due to the neutron-rootwrap.

So the solution for this could be solved by:

cp -a /usr/lib/python2.7/dist-packages/oslo/rootwarp /usr/local/lib/python2.7/dist-packages/oslo

For the compute1 node, we should mkdir /usr/local/lib/python2.7/dist-packages/oslo before the above cp
