Network management architecture
Architecture illustration
The diagrams below illustrate some of the network configurations enabled by the libvirt networking APIs
- VLAN 1. This virtual network has connectivity
        to LAN 2with traffic forwarded and NATed.
- VLAN 2. This virtual network is completely isolated from any physical LAN.
- Guest A. The first network interface is bridged
        to the physical LAN 1. The second interface is connected to a virtual networkVLAN 1.
- Guest B. The first network interface is connected
        to a virtual network VLAN 1, giving it limited NAT based connectivity to LAN2. It has a second network interface connected toVLAN 2. It acts a router allowing limited traffic between the two VLANs, thus givingGuest Cconnectivity to the physicalLAN 2.
- Guest C. The only network interface is connected
        to a virtual network VLAN 2. It has no direct connectivity to a physical LAN, relying onGuest Bto route traffic on its behalf.
