That's why I actually silenced the warning in __hvm_copy(). I would guess the reason you see this issue now is because the accesses are taking the shadow-fault path, which means you are no longer emulating real mode? ;-) Possibly we should silence the shadow code too, at least perhaps while in real mode or for a certain EIP range. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
