As part of openstack-ansible deployment, removed geneve tunnel config as you mentioned, now we have only below on neutron server

[ml2] type_drivers = vlan tenant_network_types = vlan mechanism_drivers = ovn

Same config for neutron in compute node as well, under ovn external_id

external_ids : {hostname=xxxx ovn-bridge-mappings="vlan:br-ex", ovn-cms-options="availability-zones=nova", ovn-remote="tcp:xxxx:6642,tcp:xxxxx:6642", rundir="/var/run/openvswitch", system-id="01a70eda-59bb-4e8b-870d-08eba09abae3"}

With above config, we do see below error in ovn-controller & not able to connect to SB DB

ovn-controller.log:

2025-04-29T17:38:48.508Z|00012|main|INFO|OVN internal version is : [24.03.2-20.33.0-72.6] 2025-04-29T17:38:55.206Z|00026|chassis|INFO|Need to specify an encap type and ip 2025-04-29T17:38:55.206Z|00027|chassis|INFO|Need to specify an encap type and ip 2025-04-29T17:38:55.206Z|00028|chassis|INFO|Need to specify an encap type and ip

can you please share your inputs on this ? Ideally we don't want to have ovn-*** ports to be created

ovn-controller will not start unless both ovn-encap-type and ovn-encap-ip are set, so you will need to add the geneve type driver config back. As you said in your other email that you don't allow users to create networks this should not be an issue. I guess if you're not using OVN at all and are just using vlan networks you can change to using 'openvswitch' as the mechanism driver? -Brian
