Thank you for your response and explanation, as well as your efforts on the M1 support. I guess, for now, I'll just continue to keep up with the qemu patchsets from Alexander Graf and hope they get integrated into QEMU soon so we can better report the bugs. Unless you feel I should reach out to him to report the issue. Thanks, Morgan
