Public bug reported:
Virtio interfaces are not detected correctly when booting a cloud image
with mitaka qemu-2.5 on ppc64el.
Reproduction
===========
First, I installed mitaka's ppc qemu.
# apt-get install software-properties-common
# add-apt-repository cloud-archive:mitaka
# apt-get install qemu-system
# apt-get update
# apt-get install qemu-system qemu qemu-slof qemu-system-ppc
I disabled hyperthreading on the ppc64 cores to be able to boot vms.
# ppc64_cpu --smt=off
I then tried to boot the ppc64el ubuntu cloud image.
Qemu tells that "64-bit PCI space not supported yet!". Virtio interfaces
fail to be detected.

I think that an update of qemu-slof in the mitaka's cloud-archive is needed, as it was done in Xenial here:
