Code review comment for ~powersj/cloud-init:cii-fix-kvm-tests

Integration tests nocloud-kvm work well on a fresh artful install when I do the following:
sudo apt install python3-simplestreams ubuntu-cloudimage-keyring
sudo mkdir -i /srv/citest
sudo chown me:me /srv/citest
python3 -m tests.cloud_tests run -p nocloud-kvm --os-name artful --preserve-data -data-dir restults --verbose -deb cloud-init_17.1-14-gfa66a42-1~bddeb_all.deb
