Its sounds as if your FreeBSD is a GUEST. For me, FreeBSD is the HOST.
For what its worth, the recently released nvidia driver improved something.
SO FAR, disabling GL everywhere has stopped the freezes. I've been able to run
all guests I have (one at a time for now) and none of them froze my host.
FreeBSD since version 2.2.8 [not Pro-Audio.... YET!!] (99,7% winfoes FREE)
