Thanks for the patch, and so promptly too.

Now I'm seeing several of these in bhyve.log:

"Emulating non-existing memory access to 0x81013814c"

... and the guest Win10 VM stays working - so I'd consider this a working fix.

Looking at the source for vmexit.c I now understand that the instruction
sequence error is just an artifact of the VM exiting due to the unhandled
memory access. That would explain why the instructions look very normal and
also I'm guessing need no further investigation?

Thanks again!
