Comment 3 for bug 1570218

I tested Felipe's fix with both 'ppc64' and 'ppc64el' in the deployment yaml.
With 'ppc64el', the fix works and the juju-bootstrap VM is created correctly and added into MAAS correctly.
With 'ppc64', I see the warning and the comment about it being converted internally to 'ppc64el'. The VM gets created correctly in this case, but it is not added to MAAS correctly as it still tries to use 'ppc64' in the "maas nodes new" command.
