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

+Na <em>maliBrezNetworkManager</em> poskrbi, da NetworkManager ne bo več skrbel za omrežni vmesnik, temveč bosta delovala ukaza <code>ifup</code> in <code>ifdown</code>.

+Na <em>maliNetworkManager</em> nastavi naslov IP <code>{{IP_NM}}</code> ter DNS <code>{{DNS_NM}}</code>.

+Create three virtual machines. Use <em>simpleArbiterDhcpGW</em> as the disk image for the first, <em>maliNetworkManager</em> as the disk image for the second, and <em>maliBrezNetworkManager</em> for the third. The virtual machine names can match the disks.
+
+<p>
+Make sure that on <em> maliBrezNetworkManager</em> <code>ifup</code> and <code>ifdown</code> can be used to configure the network and that NetworkManager, while still installed, will not manage the network interface. The IP should be <code>{{IP_static}}</code> and the computer should  use the server <code>{{DNS_static}}</code> for DNS.
+
+<p>
+On <em>maliNetworkManager</em>, set the IP address to <code>{{IP_NM}}</code> and use <code>{{DNS_NM}}</code> for DNS.
