Comment 1 for bug 1780780

Can we define the RCA here?
My take, copying from comment in https://github.com/rdo-infra/rdo-release/issues/10
OVS installed by openstack-infra could be and afaik is updated by the tripleoci, problem might be 2.6 -> 2.9 upgrade steps are missing i.e. restart ovs service since this is not done anymore by the RPM %post to avoid uncontrolled data plane outages during updates.
