OpenStack compute resource not showing images

I have a new but functional openstack installation installed with
"packstack --allinone". I attempted to add this as a compute resource to my
week-old Katello-2.1RC/Foreman 1.7.2 installation. It looks to me like
OpenStack has been half-added. The "Test Connection" button reports nothing
(no error, no success). The existing OpenStack VMs show up on the correct
tab with their power status. The openstack networks are showing up, but
there are two "private" networks listed instead of just one.

The images stored in glance are missing, however. The docs say to check
that the images are visible, but they don't say what you can do about it if
they're not.

No errors were reported to me via the web UI.

Any ideas?
