1. A distributed computing system, comprising:
a source computing device implementing a source hypervisor executing a virtual machine, the source computing device being connectable to a destination hypervisor implemented at a destination computing device via a network;
a source-side router coupled to the source hypervisor executing the virtual machine on the source computing device;
wherein during a migration of the virtual machine from the source hypervisor to the destination hypervisor implemented at the destination computing device,
the source-side router duplicates packets ingressing into the source-side router, the duplicated packets comprising a first set of packets and a second set of packets;
the first set of packets is routed to the virtual machine through the source hypervisor on the network; and
the second set of packets is routed to the virtual machine through the destination hypervisor on the network.
