title: Is there a command in VirtualBox for changing the base hard disk UUID location?
body: <p>I've been working on a big project with multiple virtual machines running simultaneously.</p>
  
  <p>However, I put the virtual machine base images (machine.vdi) all on the desktop and now want to move them to a folder.</p>
  
  <p>I looked at the VirtualBox conf (say, machine.vbox) and see this under HardDisks:</p>
  
  <pre><code>  &lt;HardDisks&gt;
      &lt;HardDisk uuid="{efab7241-6d7e-471c-9129-c5e4b0a43c99}" location="/home/ids/snort.vdi" format="VDI" type="Normal"&gt;
        &lt;HardDisk uuid="{18d62b60-8006-496a-b27e-2e4ee28d4551}" location="Snapshots/{18d62b60-8006-496a-b27e-2e4ee28d4551}.vdi" format="VDI"/&gt;
      &lt;/HardDisk&gt;
    &lt;/HardDisks&gt;
  </code></pre>
  
  <p>I just want to change the location of the base snapshot.</p>
  
  <p>Is there a VirtualBox command that deals specifically with that?</p>
