Hi just a quick fyi, About 2 weeks ago I did some light testing with the conntrack security group driver and the newly Merged upserspace conntrack support in ovs.
I can confirm that at least form my initial smoke tests where I Uses netcat ping and ssh to try and establish connections between two vms the Conntrack security group driver appears to function correctly with the userspace connection tracker. We have not looked at any of the performance yet but assuming it is at an acceptable level I am planning to Deprecate the learn action based driver in networking-ovs-dpdk and remove it once we have cut the stable newton Branch. We hope to do some rfc 2544 throughput testing to evaluate the performance sometime mid-September. Assuming all goes well I plan on enabling the conntrack based security group driver by default when the Networking-ovs-dpdk devstack plugin is loaded. We will also evaluate enabling the security group tests In our third party ci to ensure it continues to function correctly with ovs-dpdk. Regards Seán
