Hmm, I tried this and it still doesn't work.

First, I created a CNAME, domain2.domain1.com -> domain1.com

Next, I created XWiki.XWikiServerXwiki, added XWiki.XWikiServerClass (note: in the dropdown, it shows view.XWiki.XWikiServerClass -- could that be the problem??), set the server to www.domain1.com and the owner to XWiki.admin.  Then I created XWiki.XWikiServerDomain2, added XWiki.XWikiServerClass , set the server to domain2.domain1.com and the owner to XWiki.admin.

Then I visit www.domain1.com, it's fine.  When I visit domain2.domain1.com, it redirects me to the no such wiki page.

Thanks for all your help: The good news is that I'm learning more about XWiki and that hopefully some of this will be helpful to the next person who tries.
