title: installing libvirt in a virtual machine
body: <p>I want to install a basic architecture of OpenSatck using VirtualBox (3 VM nodes: <em>controller</em>, <em>network</em> and <em>compute</em>).
  I wanted to install libvirt within the <em>compute</em> VM but the KVM virtualization is not supported inside the VM as this command does not return any result</p>
  
  <pre class="lang-sh prettyprint-override"><code>$ egrep '^flags.*(vmx|svm)' /proc/cpuinfo
  </code></pre>
  
  <p>I ignore this and install libvirt but when I check if it's OK using this command:</p>
  
  <pre class="lang-sh prettyprint-override"><code>$ lsmod | grep kvm
  </code></pre>
  
  <p>unfortunately nothing appears.</p>
  
  <p>I don't know how can I proceed and then install the <em>compute</em> node on a virtual machine.</p>
  
  <p>Thank you.</p>
