firstly you should probably post to virtualization at freebsd.org  (CC'd)




there have been various papers presented since 2003 on the topic
but they are probably all out of date.
the mechanism currently used is descripbed a bit in the 'how to 
virtualize a module' document.

click on the 'download' link here:
http://p4db.freebsd.org/fileViewer.cgi?FSPC=//depot/projects/vimage/porting_to_vimage.txt&REV=18

It describes how things are virtualized. once you have read that
come back to this list with questions.
