20.16.9.11. Overriding the target element

To override the target element, use a management tool to make the following changes to the domain XML:

  ...
  <devices>
    <interface type='network'>
      <source network='default'/>
      <target dev='vnet1'/>
    </interface>
  </devices>
  ...

Figure 20.48. Devices - network interfaces- overriding the target element

If no target is specified, certain hypervisors will automatically generate a name for the created tun device. This name can be manually specified, however the name must not start with either 'vnet' or 'vif', which are prefixes reserved by libvirt and certain hypervisors. Manually specified targets using these prefixes will be ignored.
