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.

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.
