Recent years have seen an increasing demand for supporting real-time systems in virtualized environments. To combine real-time and virtualization, a real-time scheduler at the hypervisor level is needed to provide timing guarantees to the guest virtual machines. RT-Xen provides a suite of multi-core real-time schedulers to deliver real-time performance to domains running on the Xen hypervisor. Work is underway to incorporate RT-Xen in the Xen distribution to replace the legacy SEDF scheduler. We have implemented and empirically compared a diverse set of multicore real-time scheduling policies within the RT-Xen scheduling framework. Based on extensive experiments of different scheduling policies, we plan to submit a patch on global EDF scheduler to the xen-devel as the first step to incorporate multicore real-time scheduling support within the Xen hypervisor.
