Great to know, Phil!

We did add to the docs to explain that you couldn't choose a host any more:

http://docs.openstack.org/trunk/openstack-compute/admin/content/specify-host-to-boot-instances-on.html
and then added this page to let people know how to choose a zone

http://docs.openstack.org/trunk/openstack-compute/admin/content/specify-zone-to-boot-instances-on.html

This doc bug requests the additional information about the policy
enforcement so we can update the doc.

Thanks,
Anne
