Folks, I am trying to create lab of of ovn-bgp-agent using this blog https://ltomasbo.wordpress.com/2021/02/04/ovn-bgp-agent-testing-setup/ So far everything went well but I'm stuck at the bgp-agent installation and I encounter following error when running bgp-agent. Any suggestions? root@rack-1-host-2:/home/vagrant/bgp-agent# bgp-agent 2022-07-22 04:02:39.123 111551 INFO bgp_agent.config [-] Logging enabled! 2022-07-22 04:02:39.475 111551 CRITICAL bgp-agent [-] Unhandled error: AssertionError 2022-07-22 04:02:39.475 111551 ERROR bgp-agent Traceback (most recent call last): 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/bin/bgp-agent", line 10, in <module> 2022-07-22 04:02:39.475 111551 ERROR bgp-agent sys.exit(start()) 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/bgp_agent/agent.py", line 76, in start 2022-07-22 04:02:39.475 111551 ERROR bgp-agent bgp_agent_launcher = service.launch(config.CONF, BGPAgent()) 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/bgp_agent/agent.py", line 44, in __init__ 2022-07-22 04:02:39.475 111551 ERROR bgp-agent self.agent_driver = driver_api.AgentDriverBase.get_instance( 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/bgp_agent/platform/driver_api.py", line 25, in get_instance 2022-07-22 04:02:39.475 111551 ERROR bgp-agent agent_driver = stevedore_driver.DriverManager( 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/stevedore/driver.py", line 54, in __init__ 2022-07-22 04:02:39.475 111551 ERROR bgp-agent super(DriverManager, self).__init__( 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/stevedore/named.py", line 78, in __init__ 2022-07-22 04:02:39.475 111551 ERROR bgp-agent extensions = self._load_plugins(invoke_on_load, 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/stevedore/extension.py", line 221, in _load_plugins 2022-07-22 04:02:39.475 111551 ERROR bgp-agent ext = self._load_one_plugin(ep, 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/stevedore/named.py", line 156, in _load_one_plugin 2022-07-22 04:02:39.475 111551 ERROR bgp-agent return super(NamedExtensionManager, self)._load_one_plugin( 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/stevedore/extension.py", line 257, in _load_one_plugin 2022-07-22 04:02:39.475 111551 ERROR bgp-agent obj = plugin(*invoke_args, **invoke_kwds) 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/bgp_agent/platform/osp/ovn_bgp_driver.py", line 64, in __init__ 2022-07-22 04:02:39.475 111551 ERROR bgp-agent self._sb_idl = ovn.OvnSbIdl( 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/bgp_agent/platform/osp/utils/ovn.py", line 62, in __init__ 2022-07-22 04:02:39.475 111551 ERROR bgp-agent super(OvnSbIdl, self).__init__( 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/bgp_agent/platform/osp/utils/ovn.py", line 31, in __init__ 2022-07-22 04:02:39.475 111551 ERROR bgp-agent super(OvnIdl, self).__init__(remote, schema) 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/ovs/db/idl.py", line 283, in __init__ 2022-07-22 04:02:39.475 111551 ERROR bgp-agent schema = schema_helper.get_idl_schema() 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/ovs/db/idl.py", line 2323, in get_idl_schema 2022-07-22 04:02:39.475 111551 ERROR bgp-agent self._keep_table_columns(schema, table, columns)) 2022-07-22 04:02:39.475 111551 ERROR bgp-agent File "/usr/local/lib/python3.8/dist-packages/ovs/db/idl.py", line 2330, in _keep_table_columns 2022-07-22 04:02:39.475 111551 ERROR bgp-agent assert table_name in schema.tables 2022-07-22 04:02:39.475 111551 ERROR bgp-agent AssertionError 2022-07-22 04:02:39.475 111551 ERROR bgp-agent After googling I found one more agent at https://opendev.org/x/ovn-bgp-agent and its also throwing an error.
