Expanding to larger audience... I tested out Apex today with the ODL build Brady provided. I found there were a few updates needed in Tacker and pushed a patch to the colorado branch: https://github.com/trozet/tacker/commit/d876584242781726d2e4403e69b9d15c08765625
I then created the following nova instances/tacker VNFs: https://goo.gl/photos/F59h6V31fcQSzVFt6 The chain I created was this: testVNF4->testVNF5 The curl to the http server failed (typical classifier matching on source port 2000, dest port 80), and I don't see any packets hitting the vxlan tool on either VNF. However, I do see packets hitting the classifier. Flow gist: https://gist.github.com/trozet/3161092c62fdc6582508e7779e445bf1 I did not use the VXLAN workaround (aka the kernel host route). I thought this was not required anymore with OVS 2.5.90. Yi can you comment here? I haven't had a chance to dig into the flows yet, but if anyone sees the root cause of the problem, let me know.

I did not have time to try that as we are encountering some bugs in Netvirt and I am preparing the demo for Seattle. Please update us if you make it work with several compute nodes :).

We would need to look at the driver call when ODL creates the reverse chain, and instantiate 2 chains in tacker to do that. I just got my setup to work with the ODL Brady provided and have a clean deployment. I was going to start looking at using 2 compute nodes today and coming up with a fix for that one. Will respond to this email when I have more info/fixes.

However, it is impossible to create a classification rule on the second chain which is created (the symmetric chain), right?

Im pretty sure now you either dont set it, or explicitly set it to false. When the field is true, then ODL SFC will create a second, symmetric service chain.
