+    creation dialog, many invalid images were shown. If a project has a lot
+    of images, options can be quite long, and cause wrong selection by mistake.

+    "fedora-atomic", "coreos" and "ubuntu" would be shown.

+    Magnum UI also follow the same way as other OpenStack services
+    to read the version from OPENSTACK_API_VERSIONS of Horizon
