I sucessfully added a virtio NIC: 

    <interface type='bridge'>
      <mac address='52:54:00:a6:fb:ab'/>
      <source bridge='br0'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>


an I installed the driver from red hat  "virtio-win-0.1-22.iso". But adding a virtio 
disk fails. 

any ideas?
