It's so we can handle error reports. When someone reports that
libguestfs "hangs", it's sometimes useful to know if the BIOS was
entered or not, since it points the finger at either qemu, BIOS or
kernel. (Remember we have to be able to run on a whole variety of
Linux distros which often have old/broken/random qemu/bios/kernel).
