[2023-06-17 06:39:06] <admin1> you have br-provider in the config, but no br-vlan or br-provider in the netplan ??
[2023-06-17 06:39:27] <admin1> and for open, it should be a openvswitch type bridde
[2023-06-17 06:39:28] <admin1> bridge
[2023-06-17 06:39:30] <admin1> that is also missing
[2023-06-17 06:41:16] <admin1> and for ovn*
[2023-06-17 06:41:34] <hamidlotfi_> i',m so sorry .where is i have br-provider and br-vlan?
[2023-06-17 06:41:36] <admin1> the bridge/interface you are saying in config is missing in netplan 
[2023-06-17 06:41:38] <admin1> netplan 
[2023-06-17 06:42:01] <admin1> you are telling openstack .. my ovn is br-provider .. whereas there is no br-provider in netplan 
[2023-06-17 06:42:07] <admin1> unless this is not your network node 
[2023-06-17 06:42:56] <admin1> https://docs.openstack.org/openstack-ansible/mitaka/install-guide/targethosts-network.html -- this has a requirement for what interface is required and what is not required in which node 
[2023-06-17 06:43:20] <admin1> if you rename br-vlan to br-provider ( i never do this ) .. it still is a requirement under the new name
[2023-06-17 06:45:30] <admin1> i have to run out now .. will get back in the evening 
[2023-06-17 06:45:40] <admin1> please go via the docs again .. you are missing the requirements 
[2023-06-17 06:46:32] <hamidlotfi_> So if I build br-provider and run os-neutron-setup again the problem might be solved
[2023-06-17 06:46:50] <hamidlotfi_> Ok, thanks very much
