Looking at karaf log, there are warnings.

It looks like several nicira extension isn't supported by Carbon.
backport from nitrogen to carbon was proposed for it.

https://review.openstack.org/#/c/499825/
is the work around patch.

The netvirt is loaded and setup flows before nicira extension is loaded after openflow plugin is loaded.

the log level of the message should be error because it results in the issue which is very hard to diagnose.

yamahata do you see this issue with nitrogen and oxygen branch as well?

Comment by Anil Vishnoi [ 06/Feb/18 ]

Closing the bug. Please re-open the bug if you see this issue with nitrogen/oxygen branch.
