trace_all.py fails while tracing with "Event checksum error" about m1n1

[marcan]

That normally happens if some error happened that triggered an exception message that stepped over the MMIOTrace code. Yesterday I just pushed a rework that finally makes handling such exceptions properly possible, can you try again? (remember to always chainload m1n1 before using the hypervisor; we do not support mixing versions).

FWIW, I tried your command line and it works fine for me, on a Mac Mini with the same kernel (though of course it panics due to not being able to mount the ramdisk).

Also, hint: you probably want to pass serial=3 and cat the secondary m1n1 serial device to get the kernel log via serial instead of on the framebuffer. At least on my setup, XNU borks the HDMI output during the boot process so the single-user shell doesn't show up on there properly (not a hypervisor thing, it happens on bare metal too), but it works fine over serial. I think it's probably switching to a display mode that my capture card does not support or something like that.
