Ustvari tri navidezne računalnike. Za prvega uporabi sliko diska simpleArbiterDhcpGW, za drugega sliko diska maliNetworkManager, za tretjega sliko diska maliBrezNetworkManager. Računalnike imenujmo enako kot slike diska.

Na maliBrezNetworkManager poskrbi, da NetworkManager ne bo več skrbel za omrežni vmesnik, temveč bosta delovala ukaza ifup in ifdown.

Na maliNetworkManager nastavi naslov IP {{IP_NM}} ter DNS {{DNS_NM}}.

Na maliBrezNetworkManager nastavi naslov IP {{IP_static}} ter DNS {{DNS_static}}. ''', 'en': '''\

Create three virtual machines. Use simpleArbiterDhcpGW as the disk image for the first, maliNetworkManager as the disk image for the second, and maliBrezNetworkManager for the third. The virtual machine names can match the disks.

Make sure that on maliBrezNetworkManager ifup and ifdown can be used to configure the network and that NetworkManager, while still installed, will not manage the network interface. The IP should be {{IP_static}} and the computer should use the server {{DNS_static}} for DNS.

On maliNetworkManager, set the IP address to {{IP_NM}} and use {{DNS_NM}} for DNS.
