Abstract

Real-time virtualization is currently a hot topic, and there is much ongoing research on real-time Virtual Machines and hypervisors. However, most of the previous research focused either on reducing the latencies introduced by the virtualization stack (hypervisor, host Operating System, Virtual Machine scheduling, etc...) or analyzing the virtual CPU scheduling algorithms. Only a few works investigated the impact of the guest Operating System architecture on real-time performance or considered multiple performance metrics (latency, schedulability, startup times, resource consumption) at the same time. This paper compares various features of different virtualization technologies and guest Operating Systems, evaluating their suitability for serving real-time applications. The results indicate that solutions based on KVM (and an appropriate microvm) and the OSv unikernel can be considered viable alternatives to more traditional VMs or containers.

容器和虚拟机中的虚拟化实时工作负载

实时虚拟化是当前的热门话题，有关实时虚拟机和管理程序的研究也在不断深入。然而，以前的研究大多集中于减少虚拟化堆栈（管理程序、主机操作系统、虚拟机调度等）带来的延迟，或分析虚拟 CPU 调度算法。只有少数著作研究了客户操作系统架构对实时性能的影响，或同时考虑了多个性能指标（延迟、可调度性、启动时间、资源消耗）。本文比较了不同虚拟化技术和客户操作系统的各种特性，评估了它们对服务实时应用的适用性。结果表明，基于 KVM（和适当的 microvm）和 OSv unikernel 的解决方案可被视为更传统的虚拟机或容器的可行替代方案。

期刊介绍： The Journal of Systems Architecture: Embedded Software Design (JSA) is a journal covering all design and architectural aspects related to embedded systems and software. It ranges from the microarchitecture level via the system software level up to the application-specific architecture level. Aspects such as real-time systems, operating systems, FPGA programming, programming languages, communications (limited to analysis and the software stack), mobile systems, parallel and distributed architectures as well as additional subjects in the computer and system architecture area will fall within the scope of this journal. Technology will not be a main focus, but its use and relevance to particular designs will be. Case studies are welcome but must contribute more than just a design for a particular piece of software. Design automation of such systems including methodologies, techniques and tools for their design as well as novel designs of software components fall within the scope of this journal. Novel applications that use embedded systems are also central in this journal. While hardware is not a part of this journal hardware/software co-design methods that consider interplay between software and hardware components with and emphasis on software are also relevant here.
