The Case for Execution Replay using a Virtual Machine


Debugging grid systems is complex, mainly because of the probe effect and non reproducible execution. The probe effect arises when an attempt to monitor a system changes the behavior of that system. Moreover, two executions of a distributed system with identical inputs may behave differ- ently due to non determinism. Execution replay is a tech- nique developed to facilitate the debugging of distributed systems: a debugger first monitors the execution of a dis- tributed system and then replays it identically. Existing approaches to execution replay only partially address the probe effect and irreproducibility problem. In this paper, we argue for execution replay of distributed sys- tems using a virtual machine approach. The VM approach addresses the irreproducibility problem, it does not com- pletely avoid the probe effect. Nevertheless, we believe that the full control of the virtual hardware addresses the probe issue well enough to debug distributed system errors.
