I find it strange that you weren't prompted to update ovs to
openvswitch-2.11.0-4.el7 , which is the currently tagged version for
ovirt-4.3 and master.

If you do yum update openvswitch, doesn't it spot the update possibility ?

Sorry for the ugly logged errors; they're just noise.

Despite that, the absence of registered chassis is quite surely why
your environment is misbehaving - it looks like the ovirt update
messed up the previous config.

Could you follow the instructions at [0] to re-configure OVN ? After
the playbook finishes, please re-check your chassis table (ovn-sbctl
list chassis). You should find exactly one entry per ovirt-node.
