(not sure if my answer has been sent, sorry if duplicate) I don't touch ppc for a while but AFAIK this should work as long as you run full emulation (qemu, not kvm) as libvirt_type in nova.conf and get the qemu-system-ppc64le installed in the compute node. Assume also you get the ppc64le image to launch your instance. Expect poor performance though.
