It is difficult to diagnose without additional information… The SNAT instances are scheduled by the svc-monitor process. It queries the analytics API in order to determine whether there is any vrouter (compute node) that is available to schedule the instances. It does so after the neutron plugin creates the service-instance. You may want to check the status of the svc-monitor and also issue the queries to the analytics server that return the list of available vrouters. You can see the query here: https://github.com/Juniper/contrail-controller/blob/master/src/config/svc-monitor/svc_monitor/scheduler/vrouter_scheduler.py#L107 You may want to tcpdump the active svc-monitor and figure out whether it is doing any queries to analytics (it should as soon as it wants to schedule a service-instance that is managed by the vrouter; rather than an instance that is “nova” managed). > I also do not > see a connection for 0.0.0.0 in the vrouter introspec.
