Cool! :-)

Note that "vlan=0" won't work with the next version (2.13) of QEMU
anymore. But since that's the default, you can simply omit that
"vlan=0" in both -net options. Or if you are using the latest and
greatest QEMU v2.12 already, you can also use "-nic user,modelá000"
instead.

I guess with the ppce500 machine, you've also got to specify them
manually, too. You've got two options, virtio and USB. For virtio, try:

 -device virtio-mouse-pci -device virtio-keyboard-pci

And for USB, try something like:

 -device qemu-xhci -device usb-mouse -device usb-kbd

If "qemu-xhci" does not work, you could also try "pci-ohci" instead.
