Complex real-time systems are moving from physically isolated hosts towards common multicore computing platforms shared by multiple systems. Common platforms bring significant benefits, including reduced cost and weight, as well as increased flexibility via dynamic resource allocation. Virtualization has emerged as a promising technology for in- tegrating systems as virtual machines (VMs) on a common physical embedded computing platform.
the integration of real-time systems as VMs on a common multicore computing plat- form brings significant challenges in simultaneously meeting the real-time performance requirements of multiple systems, which in turn require fundamental advances in the underlying VM scheduling at the virtual machine monitor (VMM) level.
