Hi.

I'm trying to figure out how to deal with the configuration database.

So far I've two servers: Phosphorus and Sulphur

Phosphorus host the configuration database and an OvS instance which has :

[r...@phosphorus ~]# ovs-vsctl add-br br0
[r...@phosphorus ~]# ovs-vsctl add-port br0 eth1
[r...@phosphorus ~]# ovs-vsctl add-port br0 tap1


On Sulphur when I want to launch the OvS Daemon pointing by TCP on Phosphorus:


Jun 18 21:55:43|03538|bridge|INFO|created port tap1 on bridge br0
Jun 18 21:55:43|03539|bridge|WARN|could not create iface tap1: No such device
Jun 18 21:55:43|03540|bridge|WARN|bridge br0: port tap1 has no interfaces, 
dropping
Jun 18 21:55:43|03541|bridge|INFO|created port tap1 on bridge br0
Jun 18 21:55:43|03542|bridge|WARN|could not create iface tap1: No such device
Jun 18 21:55:43|03543|bridge|WARN|bridge br0: port tap1 has no interfaces, 
dropping
Jun 18 21:55:43|03544|bridge|INFO|created port tap1 on bridge br0
Jun 18 21:55:43|03545|bridge|WARN|could not create iface tap1: No such device
Jun 18 21:55:43|03546|bridge|WARN|bridge br0: port tap1 has no interfaces, 
dropping


As I can see the the Sulphur OvS instance try to be configured exactly the same 
way than the one on Phosphorus. 

Does it means that the configuration database is just to duplicate same 
configuration on several servers (I don't think so) ?

The next step is to configure a GRE a tunnel beween both OvS instances (no doc 
found so far).
