Expected results:
No failure

Additional info:
According to my test:
1. in the last step, only including all of "ovs0,dummy0,veth[01]" can reproduce
2. repeating the last step for many times, there is a chance to get passed. After that, even you clean up the environment and run the reproducer again, it will get passed too. But once you run "systemctl restart NetworkManager", then it can be reproduced again.
