Virtual machine (VM) based logging-and-replay technology has attracted much attention for system security, fault tolerance, and debugging. However, so far there is not a replay system designed on virtual machine monitor Xen. In this paper, XenLR presents the design and implementation of a logging tool for full system replay on Xen. To reduce the design complexity, XenLR is achieved on a lightweight VM mini OS. Our preliminary work dedicates to identify architectural non-deterministic events and… CONTINUE READING
