Hi, make sure you have at least ovirt-hosted-engine-ha-2.2.1 and the service was properly restarted. The situation you are describing can happen when you run older hosted engine agent with 4.2 ovirt-engine. It was tracked as: https://bugzilla.redhat.com/1518887 Best regards Martin Sivak On Fri, Mar 16, 2018 at 2:09 PM, Sven Achtelik <Sven.Achtelik@eps.aero> wrote:
