For the actual problem you are facing, I may need to reproduce it locally
and debug.
BTW, what's your OVN version? Did you try branch-22.09? I remembered some
minor fixes for admission control flows related to GW chassis.

Hi Tiago,
Thanks for reporting the problem. It seems you can easily reproduce the
problem, right? If so, could you enable debug log for ovn-controller before
triggering the recompute, and then we can see what flows are added during
recompute from the logs of the ofctrl module?
Thanks,

In test case acl-reject, there are no stateful ACLs and the test case works
well. However, adding a stateful ACL even with a low priority (which
shouldn't change the expected behavior of the test case) resulted in the
test case failing. Below is the change for the test case.

Hi Ben and Leonid,
As I remember you were working on the new ovn-northd that utilizes DDlog
for incremental processing. Could you share the current status?
Now that some more improvements have been made in ovn-controller and OVSDB,
the ovn-northd becomes the more obvious bottleneck for OVN use in

If you use a clustered DB, it's better to set the connect method to all
servers (or you can use a LB VIP that points to all servers), instead of
only specifying a single server, which doesn't provide desired HA.
