Efficient live wide area VM migration with IP address change using type II hypervisor

Live wide area virtual machine migration is the transfer of a virtual machine currently running and connected to clients from one host server to another host server over a Wide Area Network. In this thesis we have designed and implemented an approach for live migration while allowing the IP address of the VM to change. Our approach is efficient and with little disruption in services. The solution is divided into three key parts, runtime state migration, persistent state migration, and network connection handling. The solution uses the type 2 hypervisor Virtual Box. The runtime state migration is executed using Virtual Box´s teleportation function. The persistent state migration is split into stages executed at different point of the migration. The network connections are done using packet redirection and Dynamic DNS. Testing revealed a 358 times better in total disruption time compared to freeze and copy migration.
