Hi Sam,

                With a lithium 0.3.1 odl - ovs  setup we are able to use the rest api below. Will scriptize & use this in openstack-odl-ovs setup.

 

Thanks

Natarajan

Natarajan,

Triggering off the OF port is still early sometimes. Look for this log instead:

2015-07-02 11:13:11,589 | INFO | config-pusher | SouthboundHandler | 284 - org.opendaylight.ovsdb.openstack.net-virt - 1.1.0.Lithium | triggerUpdates

We have recently added a more deterministic method where you can do a get for a certain node. If you get the eblow url and a 200 Ok, then that means netvirt is up and ready. So you keep polling for 200Ok.

http://${ODL_IP}:8080/restconf/operational/network-topology:network-topology/topology/netvirt:1

This code is in the stable/lithium branch and master. I see Lithium 0.3.0 below so not sure if you have the official integration build or the latest off stable/lithium. The official build from a couple weeks ago does not have this url code.

Sam
