I am able to run qemu with the following commandline:
/usr/local/bin/qemu-system-ppcemb -enable-kvm -kernel uImage.bamboo
-nographic -M bamboo ppc440-angstrom-linux.img
However, when I try to use virtio instead, I get this segfault:
/usr/local/bin/qemu-system-ppcemb -enable-kvm -kernel uImage.bamboo
-drive file=ppc440-angstrom-linux.img,if=virtio -nographic -M bamboo

This patch avoids the segfault, but just gives me this message: No

FWIW, hw/ppc4xx_pci.c is my PCI controller. Do I need to add some qdev
magic to that file to make this work?
