Legacy VGA & VBE interface as a common interface is supported by many legacy and modern OS. Many installer of OS distribution use this interface to display the GUI of installer when setup a refresh new installation on bare-metal. Besides, Windows OS always use this interface to display it's BSOD, recovery mode & safe mode GUI. It is need because Windows don't include virtio-gpu driver as their in-box driver, VGA interface will be used before the virtio-gpu driver been installed. To be compatiable with the PCI bar layout of legacy VGA, the layout is refined to meet with the requirement of legacy VGA and modern virtio-gpu. BAR0: VGA Framebuffer memory, 16 MB in size.
