[warn] _default_ VirtualHost overlap on port 80, the first has precedence

This warning  occurred while restarting Apache server and two or more virtuelHost (VH) are listening on the same port, to avoid it just change listening port of  VH in http.conf file, here is an example
<VirtualHost *:8080>

NB: If you are setting ServerName for each VH you may not face this Warning.
