vip_ipv4 in the config is meant to be the IP shared between two seesaws in a HA cluster. The software expects to add and manage the IP as determined by the HA process.

It looks like you already have that IP address on the device, which may be what the engine is complaining about.

Try removing the IP from ens4 and trying again.

from seesaw.

It complains if there's no dummy interface configured but it doesn't seem to have any impact. Does the load balanced service need to be running?
