Abstract

Virtualization's architectural abstraction and encapsulation of guest systems in virtual machines facilitate migration, but existing real-time virtualization solutions are characterized by a static mapping of virtual machines to processors. This work studies migration of virtual machines with real-time constraints on homogeneous multiprocessor architectures as a service restoration in response to hardware faults. The migration policy respects real-time requirements and minimizes and predicts deadline misses based on a preceding comparison of downtime caused by the migration and slack-based computation of the virtual machine's maximum affordable downtime. The distributed design is characterized by a communication between the paravirtualized operating system and the hypervisor in order to provide the required scheduling information. The overhead regarding memory footprint, execution times, and paravirtualization effort is analyzed. The evaluation identifies ranges for virtual machine size and timing characteristics for which the approach is feasible. A reliability analysis based on a combinatorial model is used to quantify the impact of migration on reliability.

嵌入式实时系统中的虚拟机迁移容错技术

虚拟化的架构抽象和虚拟机中来宾系统的封装促进了迁移，但是现有的实时虚拟化解决方案的特点是虚拟机到处理器的静态映射。本工作研究了在同构多处理器架构下具有实时约束的虚拟机迁移作为硬件故障响应的服务恢复。迁移策略尊重实时需求，并根据先前迁移和基于空闲的虚拟机最大可承受停机时间的计算所导致的停机时间的比较，最大限度地减少和预测截止日期。分布式设计的特点是在半虚拟化的操作系统和管理程序之间进行通信，以提供所需的调度信息。分析了有关内存占用、执行时间和半虚拟化工作的开销。评估确定了该方法可行的虚拟机大小和定时特征的范围。采用基于组合模型的可靠性分析来量化迁移对可靠性的影响。
