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
use that one instead of "default" card.  Can kvm work like this?
"secondary" means secondary video card in host, and will be
"primary" in guest, right? As long as it's primary in guest, I think
you still need most of above changes.
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*.

Oh, for "secondary" in guest, it may needn't above changes. You can try it without any change.

I can't: ENOHARDWARE.

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.

I don't know. Is there any interesting usage of this secondary VGA in guest?

I *guess* windows can be told to use non-primary display.  But I've no
idea how.

Also, it certainly supports multi-display configuration somehow.  Running
most stuff on "secondary" should be possible.
