This page provides an introduction to the network port XML format.

|
|
|
This stores information about the connection between a virtual
|
|
|
|
|
interface of a virtual domain, and the virtual network it is
|
2018-08-31 14:21:34 +00:00
|
|
|
attached to.

The root element required for all virtual network ports is
|
|
|
|
|
named <code>networkport</code> and has no configurable attributes
|
|
|
|
|
The network port XML format is available <span class="since">since

The first elements provide basic metadata about the virtual
