Claim 13:
14. A method for migrating a virtual machine from a source hypervisor to a destination hypervisor, the source hypervisor and destination hypervisor connected to each other through a network via a source-side router coupled to the source hypervisor and a destination-side router coupled to the destination hypervisor, the method comprising:
initiating the migration of the virtual machine from the source hypervisor to the destination hypervisor by sending a pre-migration notification to the virtual machine to the virtual machine executed at the source hypervisor, causing the virtual machine to send a request to the source-side router to initiate a migration service to start duplicating packets;
duplicating the packets ingressing into the source-side router, the duplicated packets comprising a first set of packets and a second set of packets;
routing the first set of packets to the virtual machine through the source hypervisor; and
routing the second set of packets to the virtual machine through the destination hypervisor on the network.
