-<p> A bridge can accommodate physical devices like <code> eth0 </code>
-as well as virtual devices. On Linux systems the common approach
-to equip virtual machines with network interfaces employs the <em>
-virtual ethernet </em> (veth) device driver. This driver provides
-virtual pairs of devices where each pair represents an ethernet
-tunnel. Ethernet frames received by one end appear on its pair. To
-set up the network interface for a virtual machine, one end of the
-pair is added to a bridge on the host system while the other end
-represents the ethernet device of the virtual machine. </p>
