A method for operating a virtualized network that communicatively connects between a plurality of communication ports, instantiated for a plurality of guest operating systems executed over a plurality of hosts. The method comprises instantiating a communication port for each of the plurality of guests; performing a discovery media access control (MAC) address process of at least one destination guest of the plurality of guests by a source guest; sending a ping request from the source request to the at least one destination guest; and creating the virtualized network to allow communication between the source guest with the at least one destination guest, wherein the virtualized network is created over the physical network.
