No, I mean "secondary" on guest - no matter if it's secondary or
primary on host. So that we'll have qemu-emulated VGA as primary
and a hardware-based secondary on *guest*.
How much useful it is - it's another question. For instance, I've
no idea how windows guest will be able to use such "secondary" vga
card on guest.
