I wonder if this could be related to your CPU not supporting
unrestricted guest mode? I know it's required for some bhyve
functionality.
No, the int10 module runs the BIOS code on a software CPU.
Protected mode is simply not implemented.
I see. Well, I assume the code you reference worked without aborting at
some point. There is a related SOC idea project mentioned here ...
