Public bug reported:

First, please pardon me if this has already been dealt with in newer
releases. Our OpenStack is Train.

Our environment has thousands of images including snapshots.

When listing instances, both by command line and in the dashboard, the
instance list takes quite a while and apparently goes through all images
in the background. Please see the attached text file for an example, a
project with five instances taking over 21 seconds to list the
instances.

In contrast, using '-n' in the command will list those same instances in
less than a second. Of course, the dashboard has no such option.

If feasible, can Nova only pull the images related to the instances
rather than pulling every single image in the Glance repository?
