Arif, That was absolutely the problem. Thank you. Now on to the next thing.
On a side-note, are there any really good documentation pages for getting started with xCAT? I've been trying to follow this one (http://xcat-docs.readthedocs.io/en/stable/overview/quick_start.html), but I keep finding things that I somehow missed. If there's a better place to start, that might save me a lot of trouble.
