[OVSDB-25] Race-like behavior in programming of OpenStack instance flows causes flood+egress rules to not being programmed

Sat, 21 Jun 2014 00:08:19 +0000

Scenario:

creating 2 instances of same tenant across 2 nodes. Using ML2->ODL with GRE tunnels. About 1/2 of the times, the flows that need to be programmed to connect the 2 instances is not performed. Removing and re-creating the instance is a way to work around this issue.

Logs when flow does NOT get programmed:
