I'm trying to set up an openstack cluster, and I think I must have made a mistake when installing glance, because when I run commands related to images, such as openstack image list, I get the following error: Unexpected exception for http://:9292/v2/images: Invalid URL u'http://:9292/v2/images': No host supplied However, I haven't been able to find where this faulty URL is saved or how to fix it. Is there a specific file where it would be?
