Abstract
A system is provided for migrating a VM over a WAN. A first server has a VM. The first and second servers are operatively connected over the WAN by a virtual private local area network service. The first server migrates the VM to the second server by coping files and state of the VM to the second server without interrupting the interactive software on the VM. During a last round of migrating the VM, for packets intended for the VM on the first server, the first server buffers the packets in a buffer as buffered packets. Instead of delivering the buffered packets to the VM, the first server transmits the buffered packets to the second server. The second server plays the buffered packets to the VM migrated to and operating on the second server, such that buffered packets are played before current packets currently received from the clients are played.
