with a virtual network port. Add APIs for parsing/formatting XML docs
with the data.

+ <h1>Network XML format</h1>
+
+ <ul id="toc">
+ </ul>
+
+ <p>
+ This page provides an introduction to the network port XML format.
+ This stores information about the connection between an virtual
+ interface on a virtual domain's, and the virtual network it is
+ attached to.
+ </p>
+
+ <h2><a id="elements">Element and attribute overview</a></h2>
+
+ <p>
+ 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
+ 5.4.0</span>
+ </p>
+
+ <h3><a id="elementsMetadata">General metadata</a></h3>
+
+ <p>
+ The first elements provide basic metadata about the virtual
+ network port.
+ </p>
+
+ <pre>
+<networkport
+ <uuid>7ae63b5f-fe96-4af0-a7c3-da04ba1b3f54</uuid>
+ <owner>
+ <uuid>06578fc1-c686-46fa-bc2c-220893b466a6</uuid>
+ <name>myguest<name>
+ </owner>
+ <group>webfront<group>
+ <mac address='52:54:0:7b:35:93'/>
+ ...</pre>
+
+ <dl>
+ <dt><code>uuid</code></dt>
+ <dd>The content of the <code>uuid</code> element provides
+ a globally unique identifier for the virtual network port.
+ The format must be RFC 4122 compliant, eg <code>3e3fce45-4f53-4fa7-bb32-11f34168b82b</code>.
+ If omitted when defining/creating a new network port, a random
+ UUID is generated.</dd>
+ <dd>The <code>owner</code> node records the domain object that
+ is the owner of the network port. It contains two child nodes:
+ <dl>
+ <dt><code>uuid</code></dt>
+ <dd>The content of the <code>uuid</code> element provides
+ a globally unique identifier for the virtual domain.</dd>
+ <dt><code>name</code></dt>
+ <dd>The unique name of the virtual domain</dd>
+ </dl>
+ </dd>
+ <dt><code>group</code></dt>
+ <dd>The port group in the virtual network to which the
+ port belongs. Can be omitted if no port groups are
+ defined on the network.</dd>
+ <dt><code>mac</code></dt>
+ <dd>The <code>address</code> attribute provides the MAC
+ address of the virtual port that will be see by the
+ guest. The MAC address must not start with 0xFE as this
+ byte is reserved for use on the host side of the port.
+ </dd>
+ </dl>
+
+ <h3><a id="elementsCommon">Common elements</a></h3>
+
+ <p>
+ The following elements are common to one of more of the plug
+ types listed later
+ </p>
+
+ <pre>
+ ...
+ <bandwidth>
+ <inbound average='1000' peak='5000' floor='200' burst='1024'/>
+ <outbound average='128' peak='256' burst='256'/>
+ </bandwidth>
+ <rxfilters trustGuest='yes'/>
+ <virtualport type='802.1Qbg'>
+ <parameters managerid='11' typeid='1193047' typeidversion='2'/>
+ </virtualport>
+ ...</pre>
+
+ <dl>
+ <dt><code>bandwidth</code></dt>
+ <dd>This part of the network port XML provides setting quality of service.
+ Incoming and outgoing traffic can be shaped independently.
+ The <code>bandwidth</code> element and its child elements are described
+ in the <a href="formatnetwork.html#elementQoS">QoS</a> section of
+ the Network XML. In addition the <code>classID</code> attribute may
+ exist provide the ID of the traffic shaping class that is active.
+ </dd>
+ <dt><code>rxfilters</code></dt>
+ <dd>The <code>rxfilters</code> element property
+ <code>trustGuestRxFilters</code> provides the
+ capability for the host to detect and trust reports from the
+ guest regarding changes to the interface mac address and receive
+ filters by setting the attribute to <code>yes</code>. The default
+ setting for the attribute is <code>no</code> for security
+ reasons and support depends on the guest network device model as
+ well as the type of connection on the host - currently it is
+ only supported for the virtio device model and for macvtap
+ connections on the host.
+ </dd>
+ <dt><code>virtualport</code></dt>
+ <dd>The <code>virtualport</code> element describes metadata that
+ needs to be provided to the underlying network subsystem. It
+ is described in the domain XML
+ <a href="formatdomain.html#elementsNICS">interface documentation</a>.
+ </dd>
+ </dl>
+
+
+ <h3><a id="elementsPlug">Plugs</a></h3>
+
+ <p>
+ The <code>plug</code> element has varying content depending
+ on the value of the <code>type</code> attribute.
+ </p>
+
+ <h4><a id="elementsPlugNetwork">Network</a></h4>
+
+ <p>
+ The <code>network</code> plug type refers to a managed virtual
+ network plug that is based on a traditional software bridge
+ device privately managed by libvirt.
+ </p>
+
+ <pre>
+ ...
+ <plug type='network' bridge='virbr0'>
+ ...</pre>
+
+ <p>
+ The <code>bridge</code> attribute provides the name of the
+ privately managed bridge device associated with the virtual
+ network.
+ </p>
+
+ <h4><a id="elementsPlugNetwork">Bridge</a></h4>
+
+ <p>
+ The <code>bridge</code> plug type refers to an externally
+ managed traditional software bridge.
+ </p>
+
+ <pre>
+ ...
+ <plug type='bridge' bridge='br2'>
+ ...</pre>
+
+ <p>
+ The <code>bridge</code> attribute provides the name of the
+ externally managed bridge device associated with the virtual
+ network.
+ </p>
+
+ <h4><a id="elementsPlugNetwork">Direct</a></h4>
+
+ <p>
+ The <code>direct</code> plug type refers to an connection
+ directly to a physical network interface.
+ </p>
+
+ <pre>
+ ...
+ <plug type='direct' dev='ens3' mode='vepa'/>
+ ...</pre>
+
+ <p>
+ The <code>dev</code> attribute provides the name of the
+ physical network interface to which the port will be
+ connected. The <code>mode</code> attribute describes
+ how the connection will be setup and takes the same
+ values described in the
+ <a href="formatdomain.html#elementsNICSDirect">domain XML</a>.
+ </p>
+
+ <h4><a id="elementsPlugNetwork">Host PCI</a></h4>
+
+ <p>
+ The <code>hostdev-pci</code> plug type refers to the
+ passthrough of a physical PCI device rather than emulation.
+ </p>
+
+ <pre>
+ ...
+ <plug type='hostdev-pci' managed='yes'>
+ <driver name='vfio'/>
+ <address domain='0x0001' bus='0x02' slot='0x03' function='0x4'/>
+ </plug>
+ ...</pre>
+
+ <p>
+ The <code>managed</code> attribute indicates who is responsible for
+ managing the PCI device in the host. When set to the value <code>yes</code>
+ libvirt is responsible for automatically detaching the device from host
+ drivers and resetting it if needed. If the value is <code>no</code>,
+ some other party must ensure the device is not attached to any
+ host drivers.
+ </p>
