Ustvari tri navidezne racunalnike. Za prvega
uporabi sliko diska simpleArbiterGW, za drugega sliko diska
maliNetworkManager, za tretjega sliko diska maliBrezNetworkManager.
Racunalnike imenujmo enako kot slike diska.
Na maliBrezNetworkManager izklopi networkmanager in se loti conzole.
Na obeh rocno nastavi IP naslova ter naslova
DNS strežnikov. Naslove dobiš na simpleArbiterGW.
