Hi Michael,
I had the very same problem. You probably need to add 9pnet_virtio to the
initramfs.
# mkinitrd -f --with=9pnet_virtio /boot/initramfs-$(uname -r).img $(uname -r)
# gzip -dc /boot/initramfs-$(uname -r).img | cpio -t | grep 9pnet
usr/lib/modules/3.11.7-200.fc19.ppc64p7/kernel/net/9p/9pnet_virtio.ko
usr/lib/modules/3.11.7-200.fc19.ppc64p7/kernel/net/9p/9pnet.ko
Cheers.
