Hi folks, Yes, this project is based on Rally. We had to modify it a little bit for it to work without OpenStack. It is mentioned in the installation guide here: http://ovn-scale-test.readthedocs.io/en/latest/install.html
We started the project in 2016. Lei released an initial version, and then it became a joint effort with IBM folks. This project helped a lot in identifying scaling issues of ovn, and also verified many improvements. We talked about this in Austin OS summit ( https://www.openstack.org/videos/austin-2016/practical-ovn-architecture-deployment-and-scale-of-openstack-networking slides: https://docs.google.com/presentation/d/1HGQLHDLgHBAPjayKDZv0lIxfWhbSRGTsGSBRhvC1Ofw/edit#slide=id.g12c8454d5b_3_88 ) Current existing test scenarios are mainly creating NB port, binding on HV, and wait for sync, and it was focusing on L2 mode (no lrouters), but it should be easy to extend to more scenarios and add lrouter support, ACLs, etc. Our priority changed after the L2 mode scale tests was done, so the repo has been in hibernation mode. I am so glad Miguel come up with this before we are able to switch back on it. Scalability is really important for OVN to thrive. Miguel, please try it and feel free to ping us for any issues or any help needed from us.
