Recent years have witnessed increasing demand of running real-time embedded applications on virtualized platforms. However, existing virtualization platforms cannot provide real-time performance guarantees to virtual machines. This talk will introduce RT-Xen, a real-time virtual machine scheduling framework in the Xen hypervisor. Built based on compositional scheduling theory, RT-Xen realizes a suite of real-time schedulers including global and partitioned multi-core scheduling, fixed and dynamic priority, and different resource management schemes. RT-Xen achieves significant improvement in real-time performance over Xen’s existing credit scheduler and explores the tradeoff in real-time scheduler design in virtualized platforms. RT-Xen has been released as open-source software at https://sites.google.com/site/realtimexen/. Work is underway to incorporate RT-Xen in the Xen distribution. RT-Xen represents a promising step toward real-time virtualization for a broad range of embedded applications from automotive computing to Internet of Things.
