It seems that according to this link:  
http://support.citrix.com/servlet/KbServlet/download/15586-102-17883/XenServer_4_0_1_Product_FAQ.pdf 
that xenserver does not support BSD based Virtual Machines.  I could not 
find a similar FAQ for version 5.6.

On the other hand, it seems that, perhaps, some people have gotten it to 
work:  http://www.freebsdwiki.net/index.php/Installation_on_XenServer 
and http://forums.freebsd.org/showthread.php?t=10268 .

I also see some discussion about paravirtualization not being completely 
stable here:  
http://lists.freebsd.org/pipermail/freebsd-xen/2010-June/000512.html

Since it seems that getting stock FreeBSD to run on xenserver requires 
some custom kernel work and since PFSense isn't stock BSD, I think I 
would use a different virtualization technology or use a real hardware 
installation.
