Public bug reported: Changeset [1] introduced a validation that the local_ip specified for tunneling is actually used by one of the devices on the machine running an OVS agent.
In Fullstack, multiple tests may run concurrently, which can cause a race condition: suppose an ovs agent starts running as part of test A. It retrieves the list of all devices on the host and starts a sequential loop on them. In the mean time, some *other* fullstack test (test B) completes and deletes the devices it created. The agent has that deleted device in the list and when it will reach the device it will find out it does not exist and crash.
