    <small>Sounds like you didn't source the novarc file (extracted from
      nova.zip).<br>
      <br>
      $ source novarc<br>
      <br>
      You should also ensure that environment variables are correct,
      particularly EC2_URL, S3_URL and NOVA_URL.<br>
      In my case, these are set to <br>
      export EC2_URL=<a class="moz-txt-link-rfc2396E" href="http://172.18.0.1:8773/services/Cloud">"http://172.18.0.1:8773/services/Cloud"</a><br>
      export S3_URL=<a class="moz-txt-link-rfc2396E" href="http://172.18.0.1:3333">"http://172.18.0.1:3333"</a><br>
      export NOVA_URL=<a class="moz-txt-link-rfc2396E" href="http://172.18.0.1:8774/v1.0/">"http://172.18.0.1:8774/v1.0/"</a><br>
