And there are also reference boxes in the FreeBSD.org cluster that all FreeBSD 
developers have access to -- for example, ref7-amd64.FreeBSD.org.

I've had lots of success using Virtualbox, both hosting and hosted on, 
FreeBSD, in our teaching environment.  I also run FreeBSD with significant

managed to get a kernel debugging setup working there as yet.
