title: Enable kvm on Ubuntu running on VirtualBox on Windows
body: <p>I have a Windows machine with an Intel CPU (VMX Enabled on boot menu). I am running Ubuntu Guest on top of it using VirtualBox. I am running qemu on top of it to run another Guest OS, using kvm (the <code>-enable-kvm</code> option).</p>
  
  <p>I get the following error on trying to insert kvm-intel module:</p>
  
  <pre><code>FATAL: Error inserting kvm_intel (/lib/modules/2.6.20-ARCH/kernel/drivers/kvm/kvm-intel.ko): Operation not supported
  </code></pre>
  
  <p>I have checked for vmx flag in the guest OS and I dont see that either</p>
  
  <pre><code>$ grep vmx /proc/cpuinfo
  $
  </code></pre>
  
  <p>Is there anyway to enable kvm support in the guest Ubuntu operating system so that I can run kvm-enabled qemu on top of the Ubuntu guest machine?</p>
