Abstract
A method for live-migration of an operating system and an application is provided. The operating system runs on a first computer. The application may run on the operating system. The live-migration may be performed to a second computer while the application showing no externally detectable downtime during live-migration of the application. The method may comprise operating a tracking tool that may track and store data modifications to a disk-system of the computer in a tracking file, triggering a shutdown of the first computer while the tracking tool continues to operate in tracking mode and shut down the first computer completely. Then restarting the first computer and sending the data modifications stored prior to the complete shutdown of the first computer to the second computer, which then may be started based on the sent data, followed by starting the application such that from an external perspective no application disruption is detectable.
