There are many definitions for a virtual router, depends on the situation.

One of them is an application that simulates a router. i.e. dynamips http://www.ipflow.utc.fr/index.php/Cisco_7200_Simulator

Another one is a protocol that advertise a "virtual router" (an abstract representation of master and backup routers acting as a group). Virtual Router Redundancy Protocol (VRRP) http://en.wikipedia.org/wiki/Virtual_router_redundancy_protocol

on high end routers like CRS you can logically partition the chassis and the linecards in so called virtual routers that will have separate management, interfaces, a share of resources.

Other vendors call virtual router the equivalent of an MPLS VRF

Hope to help
