Abstract
System virtualization's consolidation in separated virtual machines provides a reasonable way to integrate formerly distinct systems into a single mixed-criticality multi-core system. We propose an adaptive resource management scheme for virtualization-based systems that have to be certified. Periodic servers and the elastic task model combine analyzability at design time with adaptability at runtime. A mode change or the enabling/disabling of tasks trigger a resource redistribution, which guarantees that a specified minimum is always allocated and obtains a fair distribution of spare capacity among the virtual machines. The partitioned scheduling and the assignment of static priorities ease certification. The scheme has the potential to improve the resource utilization and support adaptive and self-optimizing applications with strongly varying execution times.
