Guest needs VGA BIOS to initialize assigned graphics card in guest.
qemu-dm only know how to copy video BIOS of primary graphics card which
locates at 0xC0000, but don't know where are video BIOS of other
graphics cards. if want to pass-through more than one graphics cards,
must know how to get and load VGA BIOS to guest for other graphics
cards. One method is to use tools such as NiBiTor to extract VGA BIOS
from graphics card to a file, then load it to guest.
