In this project, the authors want to extend live VM migration to include:
Persistent state (file systems used by the VM)
Open network connections
Many apps running on a VM need that storage, and NAS systems may not be available in the new location.
Moving across a WAN will almost certainly involve an IP change, and we don’t want to (overly) disrupt TCP connections.
A system enables live migration of VMs that use local storage and open network connections without severely disrupting their live services.
