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 f= ix. 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! --=20 You are receiving this mail because: You are the assignee for the bug.=
