I'd like to start by clarifying that the issues you're facing are
related to the client library and not the API. Glance API v2 has
stayed the same since it was added and it keeps backwards
compatibility with older releases in the 2.x series. It does have some
differences with the API v1 but must of them relate to security models
that were improved.

That said, lets focus on the client library.

First and foremost, the immediate solution for your scripts that will
allow you to update them progressively is to add
`--os-image-api-version 1` to your ansible playbook. This is not
ideal, true.

As mentioned above, there are some incompatibilities. Some could be
brought back others won't. We've listed some of these
incompatibilities in this wiki page:

This doesn't seem to be related to the current API nor the client
release.

It'd be great if you could file a bug for this in launchpad with a bit
more details so we can debug it.

It seems that the image has been moved to an active state and then you
tried to add a location. Is that right?

Active images can't be changed. They are immutable.

Martin, Thanks for sending this out.
Happy to help debugging and any feedback on the CLI is super welcomed.
That'll help us work on a better compatibility layer.

Cheers,
Flavio
