I also like openvswitch. 

My configuration with mitaka ... 

in controller node: 

https://github.com/paradigmadigital/ansible-openstack-vcenter/blob/develop/etc_ansible/roles/networking-compute-controller/templates/ml2_conf.ini.j2
[1] 

https://github.com/paradigmadigital/ansible-openstack-vcenter/blob/develop/etc_ansible/roles/networking-compute-controller/templates/l3_agent.ini.j2


https://github.com/paradigmadigital/ansible-openstack-vcenter/blob/develop/etc_ansible/roles/networking-compute-controller/templates/openvswitch_agent.ini.j2
[2] 

in compute nodes: 

https://github.com/paradigmadigital/ansible-openstack-vcenter/blob/develop/etc_ansible/roles/kvm-hypervisor/templates/ml2_conf.ini.j2
[3] 

https://github.com/paradigmadigital/ansible-openstack-vcenter/blob/develop/etc_ansible/roles/kvm-hypervisor/templates/openvswitch_agent.ini.j2
[4] 

I don't know if this is the perfect configuration but works for my. 

Have a nice day.
