Just a nit, but this confused me initially. Maybe it should say something along the lines of create a QemuKernel.c for PlatformBootManagerLibGrub that is an exact copy of the file from PlatformBootManagerLib. Is there any way that the two libraries can use the same file rather than making an exact copy?
