We have deployed Openstack integrated with ODL through devstack all-in-one mode and networking-odl plugin. When we launch a VM ,the VM is in ACTIVE state but we are not able to ping it through the network namespace.

Karaf version installed is distribution-karaf-0.6.0-SNAPSHOT

OVS Configuration:

stack@compute:~/logs$ sudo ovs-vsctl show aa87bd0a-bdde-4ff8-8097-4b7702a922f7 Manager "tcp:192.168.100.249:6640" isconnected: true Bridge br-int Controller "tcp:192.168.100.249:6653" isconnected: true failmode: secure Port br-int Interface br-int type: internal Port "tap112f2fe8-49" Interface "tap112f2fe8-49" Port "tapb74810b2-2a" Interface "tapb74810b2-2a" type: internal ovsversion: "2.6.0"

Configuration in ml2_conf.ini related to ODL.

[agent] extensions = sfc [ml2odl] port binding_controller = pseudo-agentdb-binding password = admin username = admin url = http://192.168.100.249:8087/controlle...

Configuration in neutron.conf related to ODL.

serviceplugins = odl-router,networkingsfc.services.flowclassifier.plugin.FlowClassifierPlugin,networkingsfc.services.sfc.plugin.SfcPlugin [sfc] drivers = odl [flowclassifier] drivers = odl [OVS] ovsdbinterface = vsctl
