Systems and techniques are described for virtual machine communication and migration. A described technique includes operating server systems that are configured to run virtual machines and providing a virtual network for Internet Protocol (IP) based communications to the virtual machines. The virtual machines can be assigned network addresses, such as IP addresses, on the virtual network. Providing the virtual network can include using separate IP tunnels to effect delivery of IP packets on the virtual network to the virtual machines, respectively. The technique includes migrating a virtual machine running on a first server system to a second server system. The migrated virtual machine can maintain its assigned IP address. The technique includes updating a tunnel endpoint destination associated with the assigned IP address of the migrated virtual machine. The updated tunnel endpoint destination can be based on a network address associated with the second server system.
