Hello Yipei,
You are on the track to debug this. When you are logged into the amphora, please check the following logs to see what the amphora-agent error is: /var/log/amphora-agent.log And /var/log/syslog One of those two logs will have the error information.

The amphora can be booted successfully, and can be reached via icmp. However, octavia fails to plug vip to the amphora through the amphora client api and returns 500 status code, causing some errors as follows. |__Flow 'octavia-create-loadbalancer-flow': InternalServerError: Internal Server Error 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker Traceback (most recent call last): 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker File "/usr/local/lib/python2.7/dist-packages/taskflow/engines/action_engine/executor.py", line 53, in _execute_task 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker result = task.execute(**arguments) 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker File "/opt/stack/octavia/octavia/controller/worker/tasks/amphora_driver_tasks.py", line 240, in execute 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker amphorae_network_config) 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker File "/opt/stack/octavia/octavia/controller/worker/tasks/amphora_driver_tasks.py", line 219, in execute 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker amphora, loadbalancer, amphorae_network_config) 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker File "/opt/stack/octavia/octavia/amphorae/drivers/haproxy/rest_api_driver.py", line 137, in post_vip_plug 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker net_info) 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker File "/opt/stack/octavia/octavia/amphorae/drivers/haproxy/rest_api_driver.py", line 378, in plug_vip 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker return exc.check_exception(r) 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker File "/opt/stack/octavia/octavia/amphorae/drivers/haproxy/exceptions.py", line 32, in check_exception 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker raise responses[status_code]() 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker InternalServerError: Internal Server Error 2017-06-21 09:49:35.864 25411 ERROR octavia.controller.worker.controller_worker To fix the problem, I log in the amphora and find that there is one http server process is listening on port 9443, so I think the amphora api services is active. But do not know how to further investigate what error happens inside the amphora api service and solve it? Look forward to your valuable comments. Best regards, Yipei
