Comment 4 for bug 1620629

In testing this with a stock master (newton) devstack I disabled the security in glance API and then uploaded a tagged image using the demo user account (image 2). There are now two glance images tagged with the "amphora" tag.

stack@devstack:~/devstack$ glance image-list

When I booted a load balancer, I got the expected warning from Octavia:

2016-09-07 23:21:25.085 73535 WARNING octavia.compute.drivers.nova_driver [-] A single Glance image should be tagged with amphora tag, but 2 found. Using f0b08fe6-d5b6-4d48-916d-095c30f04bbc.

This indicated that with the current default configuration, octavia will still select the correct image.
