The devstack config we link to in the docs has been out of date for quite some time. I usually just comment out the IMAGE_URLS line so it doesn't even bother, but we should actually update it. The change falls in line with what the Heat docs recommend, and it's because of Heat that we have this configuration line in the first place. See https://docs.openstack.org/developer/heat/getting_started/on_devstack.html for their recommended config. Change-Id: I3f55c576f0e8aefa776e40509f8b7b098665ff39
