title: Start/Stop all VMs under a specific subscription
body: <p>I'm using Azure Powershell cmdlets to start/stop VMs. </p>
  
  <pre><code>Start-AzureVM [-ServiceName] &lt;String&gt; [-Name] &lt;String&gt; [ &lt;CommonParameters&gt;]
  
  Stop-AzureVM [-ServiceName] &lt;String&gt; [-Name] &lt;String&gt; [[-StayProvisioned]] [[-Force]] [ &lt;CommonParameters&gt;]
  </code></pre>
  
  <p>Is there a command to start/stop all VMs under a specific subscription rather than a single VM? If not, I'm looking for a script to run above code multiple times in parallel for each VM.</p>
