    Description

      ACS throws an null pointer exception when you try to live migrate an instance to another host in a cluster and the template of that instance has been deleted.
      I have pasted the exception below.

      Steps to reproduce the issue:
      1. create an instance from iso
      2. stop the instance
      3. create a template from the root volume
      4. create a new instance from that template
      5. leave the instance running
      6. delete the template
      7. try the live migrate the instance to another host in the cluster
      The migrate button in the web interface will not respond.
      The exception below can be found in the management-server log
