+Ustvari tri navidezne računalnike. Za enega (SimpleArbiter) uporabi sliko diska simpleArbiter. Na drugega (DHCP_server) postavi strežnika
+DHCP in DNS. Poskrbi, da bo preostali računalnik (DHCP_client) dobil naslov, ki ga prebereš na SimpleArbiterju. Na SimpleArbiterju preberi
+še ime in IP nekega računalnika (HOSTNAME_X in IP_X). Poskrbi, da bo DNS strežnik za HOSTNAME_X vrnil naslov IP_X.
