1. A distributed computing system, comprising:
a source computing device implementing a source hypervisor executing a virtual machine;
a source-side router coupled to the source hypervisor;
a destination computing device implementing a destination hypervisor; and
a destination-side router coupled to the destination hypervisor, wherein
the source hypervisor is connected to the destination hypervisor through a network; and
during a migration of the virtual machine from the source hypervisor to the destination hypervisor,
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.
