Hi, Yipei, When you play Tricircle, it’s important to know that Tricircle is the OpenStack API gateway to other OpenStack instances. In the Readme, Pod1, Pod2 are two OpenStack instances, before trying Tricircle, you can make sure the environment is normal or not by executeing command separately on Pod1, Pod2, just Nova –os-region-name Pod1, or Nova –os-region-name Pod2, in fact, because Pod1,Pod2 are two normal OpenStack instances, any command to Pod1,Pod2 should be successful. Otherwise that means there are some issue in the installation of the environment itself. Only when each bottom OpenStack can work correctly, then you can even manually add Tricircle, or through the scripts in the github to install Tircircle automaticly, as the API gateway to Pod1 and Pod2, just like you add one load balancer before your multiple web servers.
After the Tricircle was added, then the API will flow from Tricircle services like Nova-APIGW/Cinder-APIGW/Neutron API to the bottom Pod1, Pod2. So if you use Nova boot, and some error happened, you can ask question: 1. Is the command sent to the Tricircle Nova-APIGW? 2. What’ll will do for the Nova-APIGW for the next step? 3. Is the API request forwarded by Tricircle correctly to the proper bottom OpenStack? 4. Is the bottom OpenStack working normal even without Tricircle? 5. Is the API request forwarded by Tricircle includes the correct request content? 6. … You can carry the map before you try to fix the issue. And break down a big system into smaller part, and make sure which part works fine, which not in order. From the information you provided, can’t make judgment the error is occurred at Tricircle services, or bottom pod, or which pod. Don’t know which step the error occurred. And don’t know the request information, how the requested will be routed and processed, a lot of context needed to diagnose an error.

I encounter some errors when testing cross-pod L3 networking with DevStack. I followed the README.md in github, every thing goes well until I boot virtual machines with the following command: nova boot --flavor 1 --image 60a8184b-a4be-463d-a8a1-48719edc37a3 --nic net-id=76356099-f3bd-40a5-83bd-600b78b671eb --availability-zone az1 vm1 The info in the terminal is as follows: Your request was processed by a Nova API which does not support microversions (X-OpenStack-Nova-API-Version header is missing from response).
