Abstract
An operating system manages virtualized instances of hardware resources and migration enabled applications partitioned into one of multiple partitions with a separate operating system kernel running in each of the partitions. A migration event controller of the operating system manages the checkpoint and restart process during migration of a virtualized instance of at least one migration enabled application from a departure partition to an arrival partition. The migration event controller supports migration enabled applications to separately specify at least one application specific checkpoint script and restart script to be triggered by checkpoint and restart events by the migration event controller so the at least one migration enabled application can participate in performing the checkpoint and restart process for additional state information during migration of the virtualized instance from the departure partition to the arrival partition.
