Xen also uses QEMU for hw devices.
There I can boot NetBSD/amd64 as HVM guest and
dmesg | grep vga
vga0 at pci0 dev2 function 0: Cirrus Logic CL-GD5446 (rev. 0x00)
wsdisplay0 at vga0 kbdmux 1: console (80x25, vt100 emulation), using wskbd0
So it is very likely that QEMU/KVM provides a PCI VGA card.
There must be a bug before or during PCI bus scanning in order to
make a PCI attachment fail.
