Comment 4 for bug 1753511

Configuration: Kolla-Ansible 7.0.0 release on CentOS 7.5

I see the same issue with Rocky after a restart of all nodes - during testing failures.

On all compute nodes...

Running:
docker logs neutron_openvswitch_agent

Returns:
+ echo 'Running command: '\''neutron-openvswitch-agent --config-file /etc/neutron/neutron.conf --config-file /etc/
Running command: 'neutron-openvswitch-agent --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plu
