Hi Nova team, Currently nova-compute-agent uses vsctl for ovsdb interface and it does not support nova-to-ovs communication over tcp socket. We are trying to integrate Cavium Liquidio with openstack, it requires nova-to-ovs communication over a tcp connection (since ovs is offloaded to NIC). These two patches add the missing functionality. https://review.openstack.org/#/c/476612/ https://review.openstack.org/#/c/482226/ Adding native python ovsdb interface would improve the portability and performance of the nova-to-ovs communication. A similar mechanism is already present in Neutron. I added a video with a demo of these patches in action. Please have a look at it and review these patches.
