Comment 4 for bug 1751907

cdo-qa-blocker means this causes test failures in cdo-qa tests. This does, and we will have to implement a workaround to get around it. Our workaround will be to stop using not_tag, since MAAS does not support using not_tag when a pod has been added to MAAS, and instead add additional tags to all of our machines and use those as tag constraints, since MAAS doesn't ever allocate pod KVMs when a tag constraint is specified.
