Download a Fedora 19 ISO from:
http://mirrors.kernel.org/fedora-secondary/releases/19/Fedora/ppc64/iso/
Compile qemu from git (I'm using 401c227b0a1134245ec61c6c5a9997cfc963c8e4
from today).
Run qemu-system-ppc64 like this:
ppc64-softmmu/qemu-system-ppc64 -M pseries -m 4096 -hda /dev/fedora/f20ppc64 -cdrom /tmp/Fedora-19-ppc64-DVD.iso -netdev user,id=usernet,net=169.254.0.0/16 -device virtio-net-pci,netdev=usernet
Guest gets to yaboot. If you hit return, qemu segfaults:
Program received signal SIGABRT, Aborted.
