title: Unable to run a Windows 7 image on a headless Ubuntu Server that is running on VirtualBox
body: <p>Messy huh ?! I'll try not to mislead you while explaining this...
  I'm trying to simulate the environment I'll have to configure in few days. All OS's are 64-bit.
  I have Windows 7 on my development machine, running headless Ubuntu server 12.04 on VirtualBox (The OS ought to be installed on the coming server). On Ubuntu I'm trying to install "Windows 7" as a virtual machine till it's fully functional and start installing other applications on it.</p>
  
  <p>The image (Windows 7 hosted on the headless Ubuntu server) starts and shows that windows is "Loading files", and instead of starting the installation process, it shows the message: <code>Attempting to load a 64 bit application however this cpu is not compatible with 64-bit mode</code>.</p>
  
  <p>Here is the Windows 7 virtual machine info:</p>

  <p>So what am I missing here ? May be Is it not possible to have hardware virtualization on a virtual machine (Headless Ubuntu server) ?</p>
