Rabi,

As you observed, I have uploaded two testing patches [1][2] that depends on your fix patch [3] and the reverted patch [4] respectively. An observation is that the test "gate-functional-dsvm-magnum-mesos" failed in [1], but passed in [2]. That implies the reverted patch does resolve an issue (although I am not sure exactly how).

I did notice there are several 404 errors from Neutron, but those errors exist in successful tests as well so I don't think they are the root cause.

[4] https://review.openstack.org/#/c/278575/

Best regards,
Hongbin

Hi,

We did some analysis of the issue you are facing.

One of the issues from heat side is, we convert None(singleton) resource references to 'None'(string) and the translation logic is not ignoring them. Though we don't apply translation rules to resource references[1].We don't see this issue after this patch[2].

The issue you mentioned below with respect to SD and SDG, does not look like something to do with this patch. I also see the similar issues when you tested with the reverted patch[3].

I also noticed that there are some 404 from neutron in the engine logs[4] for the test patch. 
I did not notice them when I tested locally with the templates you had provided.


Having said that, we can still revert the patch, if that resolves your issue.
