ERROR neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [-] Tunneling can't be enabled with invalid local_ip '10.113.4.9'. IP couldn't be found on this host's interfaces.ESC[00m

Environment

• Platform9 Managed OpenStack All Versions

• Neutron

Cause

• In ml2_conf.ini file the local_ip value is set as 10.113.4.9

None

$ cat /opt/pf9/etc/pf9-neutron-ovs-agent/ml2_conf.ini | grep local_iplocal_ip = 10.113.4.9

This IP is not assigned to any interface on this host.

• On the other working hosts, we can see that a correct IP is assigned.

None

Resolution

To fix this we need to assign a correct IP for local_ip value as assigned to a network interface by editing it in the file /opt/pf9/etc/pf9-neutron-ovs-agent/ml2_conf.ini.
