title: Unable to Launch Windows Phone Emulator
body: <p>I am trying to run unit tests on our CI server. When i run the following command it tries to launch emulator but fails with the following message</p>
  
  <pre><code>vstest.console.exe myxapfile.xap
  </code></pre>
  
  <p>Error Message</p>
  
  <pre><code>The Windows Phone Emulator wasn't able to ensure the virtual machine was running:
  
  Something happened while starting a virtual machine: 'Emulator WVGA 512MB.ttmaltiparmak' failed to start. (Virtual machine ID 1350ADCE-CC35-4615-BFD5-250179F789EE)
  
  The Virtual Machine Management Service failed to start the virtual machine 'Emulator WVGA
  512MB.ttmaltiparmak' because one of the Hyper-V components is not running (Virtual machine ID
  1350ADCE-CC35-4615-BFD5-250179F789EE).
  </code></pre>
  
  <p>My system seems to support following requirements (But it is a virtual machine is it a problem?)</p>
  
  <ul>
  <li>64 bit windows 8</li>
  <li>SLAT Support</li>
  <li>4 GB ram</li>
  <li>Hyper-V is on</li>
  </ul>
  
  <p><strong><em>Further trials and results:</em></strong> </p>
  
  <p>I tried removing and re-adding hyper-v through add-remove programs and now <strong>Hyper-V Platform</strong> option is disabled and i can not activate it :S Gilson Banin  says that hyper-v installation is not possible on virtual machines, as i mentioned before our server is a virtual machine is it right that i cant use hyper-v on a virtual machine? </p>
