<p>
The network access of direct attached virtual machines can be
managed by the hardware switch to which the physical interface
of the host machine is connected to.
<p>
The interface can have additional parameters as shown below,
if the switch is conforming to the IEEE 802.1Qbg standard.
The parameters of the virtualport element are documented in more detail
in the IEEE 802.1Qbg standard. The values are network specific and
should be provided by the network administrator. In 802.1Qbg terms,
the Virtual Station Interface (VSI) represents the virtual interface
of a virtual machine.

<dt><code>managerid</code></dt>
<dd>The VSI Manager ID identifies the database containing the VSI type
and instance definitions. This is an integer value and the
value 0 is reserved.</dd>
<dt><code>typeid</code></dt>
<dd>The VSI Type ID identifies a VSI type characterizing the network
access. VSI types are typically managed by network administrator.
This is an integer value.
</dd>
<dt><code>typeidversion</code></dt>
<dd>The VSI Type Version allows multiple versions of a VSI Type.
This is an integer value.
</dd>
<dt><code>instanceid</code></dt>
<dd>The VSI Instance ID Identifier is generated when a VSI instance
(i.e. a virtual interface of a virtual machine) is created.
This is a globally unique identifier.
