Live migration is a mechanism that allows a VM to be moved from one host to another while the guest operating system is running. Current live migration implementations are able to maintain network connectivity in a LAN. However, the same techniques cannot be applied for live migration over the Internet. We present a solution based on PMIPv6, a light-weight mobility protocol standardized by IETF. PMIPv6 handles node mobility without requiring any support from the moving nodes. In addition, PMIPv6 works with IPv4, IPv6 and dual-stack nodes. We have setup a testbed to measure the performance of live migration in a PMIPv6 network. Our results show that network connectivity is successfully maintained with little signaling overhead and short VM downtime. As far as we know, this is the first time PMIPv6 is used to enable live migration beyond the scope of a LAN.
