Did you get to run FreeBSD in HVM mode? What version of Xen, and who was playing the dom0? The reason for the question is that I have patchy experience with HVM: while I have Windows XP Professional running happily, OpenSolaris 2008.5 would lock up on the regular basis. I am running Xen 3.2.1 with OpenSuse x86_64 11.0 in the dom0.
