Dear all,
  I followed the documentation at https://wiki.openstack.org/wiki/StarlingX/Networking/TSN to enable PCI passthrough so that Starlingx can support TSN. In Starlingx AIO host, I have i210 network interface. In the documentation, it mentioned about creating "nova-tsn-pt.yaml". 

1/ Inside this file, is the "{host_ip}" point to my OAM IP address? 

2/ The "{controller_name}" can I replace with the default name "controller-0"?

When I issue "system helm-override-update stx-openstack nova openstack --values nova-tsn-pt.yaml" and "system application-apply stx-openstack", it failed with the error below:

How can I solve the above error? 

I am using the latest Starlingx V5.0.1 with the Openstack "stx-openstack-1.0-116-centos-stable-latest.tgz". Thanks for any information!
