title: Create virtual machine using qcow2 as storage (virt-manager)
body: <p>I am running debian wheezy. virt-manager is version 0.9.1. As per online documentation it should be possible to create a virtual machine using qcow2 storage, as per <a href="http://opennodecloud.com/documentation/howtos/kvm-vm-management-with-virt-manager-gui/" rel="nofollow noreferrer">this link</a>.</p>
  
  <p>However from my version the dialog box looks rather like this:</p>
  
  <p><img src="https://i.stack.imgur.com/33qgE.png" alt="enter image description here"></p>
  
  <p>And during install process it is not possible to select anything but 'raw' storage:</p>

  <p>I have tried creating the the qcow2 image <a href="http://virt-tools.org/learning/install-with-command-line/#disk" rel="nofollow noreferrer">outside</a> of the interface using:</p>
  
  <pre><code># qemu-img create -f qcow2 guest.qcow2  8192
  Formatting 'guest.qcow2', fmt=qcow2 size=8192 encryption=off cluster_size=65536 
  </code></pre>
  
  <p>For some reason the file size does look kind of odd:</p>
  
  <pre><code># ls -altr guest.qcow2
  -rw-r--r-- 1 root root 197120 juil. 24 15:13 guest.qcow2
  </code></pre>
  
  <p>If I select this storage and then pursue with a regular Window 7 pro installation, the installer report that the disk size is simply 0 and cannot continue.</p>
  
  <p>Any recommendation on where to do from here ?</p>
