That's a triple fault (from sys/amd64/vmm/intel/vmcs.h)

anyone have a decoder ring?
A few questions to narrow this down:
Did you add WITNESS to the guest kernel or the host kernel when this happened?
yes I added it to the guest kernel.. I suspect it ay be related to
this, especially since there was a kernel module loaded that was not
recompiled.
I'm trying to ascertain now whether a withness kernel requires special
handling for its modules.
Is this readily reproducible?
don't know yet.
Can you share the host and guest revision numbers?
guest is custom sources based on stable-10 on the same day as 10.0 was
released.basically whatever svn revision# was on 10.0 but on the
stable branch.
host is
FreeBSD 10.1-BETA1 #0 r271671: Tue Sep 16 09:31:23 PDT 2014
