<div>Hi,</div>
<div>Yes, you are correct. That patch is the culprit (my bad and once again humble apologies)</div>
<div><br>
</div>
<div>Regarding the AZ support I think that we need to do the following:</div>
<ol>
<li>Have this in a separate topic until it is complete. I have a number of concerns here:
<ol>
<li>The upgrade impact on Nova. Today in Nova one can have N AZ’s and they will all work on the same virtual networks. It is not clear how this will work here and if the networks can be shared across AZ’s (maybe this was discussed and I am missing somehing)</li><li>A few weeks ago Monty raised concerns about floating IP support. I think that this will be required for AZ support. In the past one could have a shared network between AZ’s and now they will need two isolated networks</li></ol>
</li><li>In Nova on of the top priority features over the last few cycles has been cells. At the moment there is no cell support for Neutron. I feel that the AZ support is someone what related and maybe we should try and kill 2 birds with one stone here and have
the cell support combined if possible. I think that this is certainly something that should be a cross project summit discussion.</li></ol>
<div>Thanks</div>

<div>Hi,</div>
<div>It appears that the addition has broken the vmware_nsx plugin (<a href="https://review.openstack.org/183369" target="_blank">https://review.openstack.org/183369</a>). We are still debugging. Would it be worthwhile considering adding this support as a feature
branch and then when the entire feature is ready that we merge it to the tree. This will enable the external vendors to be alive and kicking.</div>
</div>
</blockquote>
<div><br>
</div>
<div>Please let us know how we can help you to fix it. The CI hasn't voted on this patch since May 14, so clearly the breakage flew under the radar.</div>
