Hello fellow OpenStackers -

We are using Openstack Stein, VMWare Vcenter (and esxi), as well as NSX-T for our deployment. We are using cloud-init, CentOS7, and also the VMWare NSX plugin. Our metadata proxies are being handled by NSX-T. Networking is setup and configured; however, when instances are deployed, during the boot process (when cloud-init is initializing) the machine has a problem with the metadata service.

During boot, after GRUB appears cloud-init is attempting some kind of transaction with the metadata proxy, fails, and loops for 2 minutes. Next, it attempts another action, fails for two minutes and then moves on to complete the booting of the operating system.

Message during boot states:
Finally, stating:
Next error states:
Lastly to add:

I can use curl to retrieve data from the controller:8775 where nova resides successfully. However, if I attempt to curl the metadata proxy on the link local address from within the same segment I get a 502 bad gateway message.

Please let me know if you have any insight or if there is more information I can provide.

Thank you!
