Following bz https://bugzilla.redhat.com/show_bug.cgi?id=1445030 and patches : > [1] https://review.openstack.org/#/c/461734/ > [2] https://review.openstack.org/#/c/462035/ We are able to run a successful deployment with openvswitch and cisco_ucsm mechanism driver BUT after that, we are unable to instantiate an ovs ml2 VM over the overcloud, because I think of [2] where we set : OS::TripleO::Services::ComputeNeutronOvsAgent: OS::Heat::None OS::TripleO::Services::ComputeNeutronCorePlugin: OS::Heat::None We need to look at what is missing here to have both ml2 mechanism drivers working fine. Customers may not only need sr-iov instances on a compute node. Thanks.
