In my mind network virtualization can be accomplished in several ways. Anytime a single physical network device is configured to have discreet domains in regard to frame or packet forwarding it has been virtualized.
Multiple Vlans on a layer 2 switch is virtualization; something the industry has been doing long before the virtualization craze. On Cisco equipment implementing multiple VRF (Virtual Route Forwarding) instances and assigning them to interfaces will create an environment where a single router has multiple discreet routing domains. Some physical network devices are capable of hosting multiple contexts; interfaces are assigned to a virtual network device in the form of a context. This technique virtualizes the management plane as well as the forwarding plane. The combination of all these virtualization techniques results in the virtualized network nirvana.
