Public bug reported:

If the image has an architecture property, the libvirt utils do *not*
canonicalize that.

``utils.get_arch(image_meta)`` can possibly return "S390X" (<= upper
case). The canonicalized version should be "s390x" (<= lower case).

This will be an issue when a user adds the property "architecture=S390X"
on an image.

I used "S390X" as an arbitrary example. The real issue here is the lower
case and upper case thing.

See method ``get_arch(image_meta)`` in https://github.com/openstack/nova/blob/master/nova/virt/libvirt/utils.py#L557
See method ``canonicalize(name)`` in https://github.com/openstack/nova/blob/master/nova/compute/arch.py#L147
