Description Miguel Angel Ajo 2019-02-05 22:09:08 UTC

Description of problem:

We see this on the ovs-vswitchd.logs of the hosts:

can be fixed by:

sudo ovs-vsctl set-fail-mode br-ex standalone
sudo ovs-vsctl del-controller br-ex

also all other bridge mapped bridges, this loop here looks like a good place to do it:

According to our records, this should be resolved by python-networking-ovn-5.0.2-0.20190307204430.6a774a0.el7ost.  This build is available now.
