</h2>
<p>
The diagrams below illustrate some of the network configurations
enabled by the libvirt networking APIs
</p>
<ul><li><strong>VLAN 1</strong>. This virtual network has connectivity
to <code>LAN 2</code> with traffic forwarded and NATed.
</li><li><strong>VLAN 2</strong>. This virtual network is completely
isolated from any physical LAN.
</li><li><strong>Guest A</strong>. The first network interface is bridged
to the physical <code>LAN 1</code>. The second interface is connected
to a virtual network <code>VLAN 1</code>.
</li><li><strong>Guest B</strong>. The first network interface is connected
to a virtual network <code>VLAN 1</code>, giving it limited NAT
based connectivity to LAN2. It has a second network interface
connected to <code>VLAN 2</code>. It acts a router allowing limited
traffic between the two VLANs, thus giving <code>Guest C</code>
connectivity to the physical <code>LAN 2</code>.
</li><li><strong>Guest C</strong>. The only network interface is connected
to a virtual network <code>VLAN 2</code>. It has no direct connectivity
to a physical LAN, relying on <code>Guest B</code> to route traffic
on its behalf.
</li></ul>
