Abstract

Partition migrations are scheduled between virtual partitions of a virtually partitioned data processing system. The virtually partitioned data processing system is a tickless system in which a periodic timer interrupt is not guaranteed to be sent to the processor at a defined time interval. A request is received for a partition migration. Gaps between scheduled timer interrupts are identified. The partition migration is then scheduled to occur within the largest gap.
