Logical Domains 1.3 Administration Guide

Virtual Network Device

A virtual network (vnet) device is a virtual device that is defined in a domain connected to a virtual switch. A virtual network device is managed by the virtual network driver, and it is connected to a virtual network through the hypervisor using logical domain channels (LDCs).

A virtual network device can be used as a network interface with the name vnetn, which can be used like any regular network interface and configured with the ifconfig(1M) command.

Figure 7–1 Setting Up a Virtual Network

Diagram shows how to set up a virtual network as described in the text.

Following is a explanation for the example in Figure 7–1.

Basically the virtual switch behaves like a regular physical network switch and switches network packets between the different systems, such as guest domains, service domain, and physical network, to which it is connected.
