[Merge] ~rodrigo-barbieri2010/ubuntu/+source/nova:bug/1821755_stein into ~ubuntu-openstack-dev/ubuntu/+source/nova:stable/stein

[Chris MacNaughton]

The change looks OK but the related bug has no Stein targets, it would be good to get bug tasks raised for the cloud-archive (and nova in Ubuntu as well) to track getting this patch into distro
