Hi, opencontrail-vrouter-netns is not a deamon, just a script run by vrouter agents on compute node to setup a Linux namespace that will be in charge of the masquerading between private and public networks. As Jakub asked, you just need to have that binary available on the compute node and executable. The svc_monitor log 'SvcMonitorLog: No vrouter available for VM ' you mentioned means the svc_monitor service was not able to find any available vrouter agent to schedule Linux namespace. The svc_monitor lists vrouter from the Contrail VNC API so you have beforehand to provision vrouters (look to the script provision_vrouter.py for that). You can check which vrouters are provisioned by listing the resource collection 'virtual-routers' from the VNC API (http://<CONTRAIL API HOST IP/NAME>:8082/virtual-routers). Then the svc_monitor uses the analytics UVEs API (http://<CONTRAIL API HOST IP/NAME>:8081/analytics/uves/vrouter/<VROUTER NAME>*?cfilt=NodeStatus:process_status) to determine if vrouters are in correct state before selects them.
