Live migration of virtual machines between clouds would offer a way to adapt to resource dynamicity. However, live migration is not possible across different clouds when using a standard networking environment. In order to allow inter-cloud live virtual machine migration, we leveraged ViNe, a virtual network implementation developed at the University of Florida, providing all-to-all communication to nodes in grid or clouds environments, even in the presence of firewalls, NAT or private IP addressing.

We modified ViNe to detect virtual machine mobility and reconfigure itself so that communications can remain uninterrupted. Our approach is based on standard networking techniques such as ARP proxy and gratuitous ARP messages, and leverages the ViNe infrastructure to establish tunnels between multiple clouds.
