<h1>Network management architecture</h1>
|

|
|
<h2>Architecture illustration</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>
