--verbose please. Which guest? Which firmware?
ACPI poweroff with seabios works just fine. If APM support in seabios
uses something else it should be switched to use the same hardware ports
ACPI uses for poweroff (some piix4 pm device register I think) instead
of the debug ports which where never meant to be used that way.
Does bochs bios run on recent qemu versions in the first place?
cheers,
Gerd
