I want to thank everyone that's been working on this issue profusely.<br>
This exposed a release critical bug in Nova that we would not have<br>
caught otherwise. Finding that before milestone 3 is a huge win and<br>
gives us a lot more options in fixing it correctly.<br>
<br>
I think we've got the proper fix now -<br>
<a href="https://review.openstack.org/#/c/279721/" target="_blank">https://review.openstack.org/#/c/279721/</a> (fingers crossed). The metadata<br>
server is one of the least tested components we've got on the Nova side,<br>
so I'll be looking at ways to fix that problem and hopefully avoid<br>
situations like this again.<o:p></o:p></p>
