Comment 9 for bug 1317880

Unless I'm missing something, this isn't breaking Horizon functionality (the instance launches and works) although it does mean we're showing less information to the user than we'd like. Looking at the JSON reply when calling to the server details though, at this point there doesn't seem to be anything that can be done in Horizon to improve this. The revert mentions an image_ref attribute but it doesn't look like this is returned.
