that? Are
Currently VGA pass-through is not supported in KVM. It needs much
work to support it.
Here's what I know of:
- load the vga bios at 0xc
- implement whatever main bios interfaces the vga vios expects
- pass through the vga I/O ports

But how about using it as a secondary video card? Like, I can
plug another add-on vga card into a free PCI slot and tell X to
