Abstract
A method for routing packets includes receiving an outbound packet issued by a first virtual machine, wherein the first virtual machine is located on a host, determining a packet destination associated with the outbound packet, querying a routing table for a routing entry corresponding to the packet destination, wherein the routing table comprises a first routing entry referencing an external host and a second routing entry referencing a second virtual machine, wherein the second virtual machine is located on the host, if the routing entry corresponding to the packet destination is the first routing entry, passing the packet to the external host, and if the routing entry corresponding to the packet destination is the second routing entry, passing the packet to the second virtual machine.
