Re: Openstack-ODL integration issues in stable/kilo + Lithium 0.3.0
Thanks for the inputs.
This allinone setup creates bridge, network & tenants.
We tried setting ODL_BOOT_WAIT to 300 and in one of two attempts br-int, OF port connection was all fine.
We are trying to get this set-up consistent…
We wait for below logs, before issuing a ovs-vsctl set-manager. Hope these are the ones to look for before doing a set-manager ?
Starting point is this
| INFO | Event Dispatcher | FeaturesServiceImpl | 20 - org.apache.karaf.features.core - 3.0.3 | Installing feature odl-ovsdb-openstack 1.2.0-SNAPSHOT
OVSDB socket is active
| INFO | entLoopGroup-7-1 | LoggingHandler | 106 - io.netty.common - 4.0.26.Final | [id: 0xc3b7928a, /0:0:0:0:0:0:0:0:6640] ACTIVE
OF socket is ready for listening
INFO | Thread-59 | TcpHandler | 256 - org.opendaylight.openflowjava.openflow-protocol-impl - 0.6.0.SNAPSHOT | Switch listener started and ready to accept incoming tcp/tls connections on port: 6653
Start to OF socket ready is typically a little over 3 mins in our OS-ODL setup (4GB RAM each in control/compute node) .

what all does the allinone setup do besides stack and start odl? Meaning does it try to create any bridges or networks?
could you modify the allinone to add a 60s or 90s sleep in between when the ovsdb node manager is set and when odl starts? Or switch from all in one to external? I think what is happening is that odl is starting but it takes a while to get to a resting state. netvirt is the last service to run since it depends on neutron, openflowplugin and the southbound. Those can take a long time to start and then when netvirt finally starts it can take another 30s or so to start. So during that time if the stack is trying to connect to odl there can be issues.
