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.
<p>
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>.
<p>
Na <em>maliNetworkManager</em> nastavi naslov IP <code>{{IP_NM}}</code> ter DNS <code>{{DNS_NM}}</code>.
<p>
Na <em>maliBrezNetworkManager</em> nastavi naslov IP <code>{{IP_static}}</code> ter DNS <code>{{DNS_static}}</code>.

<p>
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.
