Ok, that's likely not the issue then. I assume the way you access each host is via an IP assigned to an OVS bridge or an interface that somehow depends on OVS? On Apr 28, 2017 12:04, "Gustavo Randich" wrote: > Hi Kevin, we are using the default listen address of loopback interface: > > # grep -r

Ok. That would solve some of the problem for us, but we’d still be losing the redundancy. We could do some HAProxy tricks to route around downed services, but it wouldn’t handle the case when that one physical box is down. Is there some downside to allowing endpoint_override to remain a list?
