Hi Yatindra, To enable DNS you need to create a yaml file and then override helm: cat > neutron-overrides.yaml <<EOF conf: neutron: DEFAULT: dns_domain: wrs_dns.com plugins: ml2_conf: ml2: extension_drivers: dns EOF # update the neutron overrides and apply to stx-openstack source /etc/platform/openrc system helm-override-update stx-openstack neutron openstack --values neutron-overrides.yaml system application-apply stx-openstack I notice that you have already changed the configuration. Could you please check the configuration by following command: kubectl get pod -n openstack | grep neutron-ovs kubectl exec -it -n openstack $neutron-ovs-agent bash cat /etc/neutron/neutron.conf | grep dns_domain cat /etc/neutron/plugins/ml2/ml2_conf.ini | grep extension_drivers Could you please attach some logs for failing to attach the port to the VM. (like nova-conductor, nova-compute, nova-scheduler, neutron-server, neutron-ovs-agent, openstack server show vm) For Designate component provide DNS, the following guide can be referenced: https://docs.openstack.org/mitaka/networking-guide/config-dns-int.html#confi... You need to use helm override to change the configuration.

I saw in the openstack documentation https://docs.openstack.org/mitaka/networking-guide/config-dns-int.html but unable to associate a port to VM, it fails. I had changed the configuration file in neutron helm and added as below 1. dns_domain = stx-mu.org and also added the DNS external driver in ml2 plugin as below. extension_drivers = port_security,dns While researching more about the DNS configuration in the Openstack, I found that Designate component provide DNS as service. Do we have it in StarlingX or any plan for it.
