    Abstract: Methods, computer program products, and network authority devices are presented. The methods include, for instance: updating a source network with migration information of a virtual machine to redirect network traffic for the virtual machine to a destination network; and updating at least one remote network with the migration information of the virtual machine. In one embodiment, the updating includes updating the source network concurrent with a migration of the virtual machine to minimize interruption of the network traffic. In another embodiment, the updating includes updating a network device of the source network to forward the network traffic for the virtual machine to another network device of the destination network. In a further embodiment, the updating includes updating the source network to redirect the network traffic from at least one client on the at least one remote network.

    Abstract: For logical multicasting in overlay networks, at a data processing system, an original unicast packet is received from a first component in a first computing node in an overlay network. To cause multicasting in the overlay network the received original unicast packet was unicast by the first computing node only to the data processing system, and a multicast data structure for the overlay network is maintained only by the data processing system, the multicast data structure containing information of each receiver that is configured to receive unicast packets during logical multicasting in the overlay network. From a set of subscriber receivers in the multicast data structure, a subset of the subscriber receivers is selected. A copy of the original unicast packet is unicast to each subscriber receiver in the subset.

    Abstract: Methods, computer program products, and systems are presented. The methods include, for instance: locating, by one or more processor, at least one virtual machine within a virtual network, wherein gratuitous address resolution functionality of the at least one virtual machine is inactive; and providing, by the one or more processor, location information of the at least one virtual machine. In one embodiment, the locating comprises: receiving an IP address of the at least one virtual machine; and selecting a virtual machine hosting network device from a computing network node table, where the computing network node table comprises at least one network connection record of the silent virtual machine network device hosting a silent virtual machine having a known MAC address and an unknown IP address; and querying the silent virtual machine network device for a MAC address corresponding to the IP address of the at least one virtual machine.
