<span class="since">Since 2.0.0</span> network devices of type
"ethernet" can optionally be provided one or more IP addresses
and one or more routes to set on the <b>host</b> side of the
network device. These are configured as subelements of
the <code>&lt;source&gt;</code> element of the interface, and
have the same attributes as the similarly named elements used to
configure the guest side of the interface (described above).
