 +</code>
  
-  virsh define test-1.example.com.xml+Ahora obtenemos el listado de VMS: 
 + 
 +  virsh list --all
      
 +Y para cada una de ellas obtenemos la MAC address:
 +
 +  virsh dumpxml vm-1.example.com | grep "mac address" | awk '{print $2}' | cut -d "'" -f2
 +
 +TODO: hacer un script en bash que lo haga
 +
 +Finalmente nos aseguramos que la nueva MAC generada es unica.

 +5. Definir la nueva VM:
