  <p><p>I have created a drive with meta-data and user-data:</p>
  
  <p><p>meta-data:<br/>
  instance-id: iid-local01<br/>
  local-hostname: cloudimg<br/></p>
  
  <p>user-data:<br/>
  <p>#cloud-config<br/>
  write_files:<br/>
    - path: /test.txt<br/>
      content: |<br/>
        Here is a line</p>
  
  <p>But the file is not getting created. Can you help in solving this issue? Or in disabling the cloud-init from contacting the metadata services.</p>
