  1. Install VirtualBox on your machine
  2. Disable login credential: $ VBoxManage setproperty websrvauthlibrary null
  3. Download and uncompress the following image https://s3.amazonaws.com/vmfest-images/ubuntu-10-10-64bit-server.vdi.gz
  4. Clone the image to the directory where you want it to be permanently stored and make it immutable:
      * $ VBoxManage clonehd /path/to/downloaded/ubuntu-10-10-64bit-server.vdi /path/to/permanent/location/ubuntu...-server.vdi
         * This should produce a uuid for your new image. Keep it around
      * $ VBoxManage modifyhd /path/to/permanent/location/ubuntu-10-10-64bit-server.vdi --type immutable
  5. Start VirtualBox (the GUI) and
    1. Create an new image Linux - Ubuntu (64bit)
    2. Select "Use existing hard disk" and if your newly cloned image doesn't appear in the drop-down list, click on the folder icon and find the image in your hard disk (the one you just cloned)
