Public bug reported:

When verifying Glance image signatures, Nova does not report a
meaningful error message to the end user. Instead, Nova gives the end
user a "No hosts available" message.

How to verify this behavior:
- Enable Nova's verify_glance_signatures configuration flag
- Upload an image to Glance with incorrect or missing signature metadata
- Attempt to boot an instance of this image via the Nova CLI

You should get an error message with the text "No valid host was found.
There are not enough hosts available". This does not describe the
failure and will lead the end user to think there is an issue with the
storage on the compute node.
