VIDEZZO: Dependency-aware Virtual Device Fuzzing

Mathias Josef Payer, Flavio Toffalini, Qiang Liu

A virtual machine interacts with its host environment through virtual devices, driven by virtual device messages, e.g., I/O operations. By issuing crafted messages, an adversary can exploit a vulnerability in a virtual device to escape the virtual machine, ...

Worst-Case Delay Analysis of Time-Sensitive Networks with Network Calculus

Seyed Mohammadhossein Tabatabaee

Time-sensitive networks, as in the context of IEEE Time-Sensitive Networking (TSN) and IETF Deterministic Networking (DetNet), offer deterministic services with guaranteed bounded latency in order to support safety-critical applications. In this thesis, we ...

A system design for elastically scaling transaction processing engines in virtualized servers

Anastasia Ailamaki, Angelos Christos Anadiotis, Raja Appuswamy, Hillel Avni

Online Transaction Processing (OLTP) deployments are migrating from on-premise to cloud settings in order to exploit the elasticity of cloud infrastructure which allows them to adapt to workload variations. However, cloud adaptation comes at the cost of re ...

Self-Organized Laboratories for Smart Campus

Denis Gillet, Christophe Salzmann

A smart campus provides students who are geographically scattered with online tools to get access to learning resources and laboratories. Although these remote laboratories have the potential and capabilities to implement different learning experiments, mo ...

Experimental Validation of the Suitability of Virtualization-Based Replication for Fault Tolerance in Real-Time Control of Electric Grids

Jean-Yves Le Boudec, Wajeb Saab, Jalal Mostafa, Seyed Alireza Sanaee Kohroudi

Real-time control systems (RTCSs) perform complex control and require low response times. They typically use third-party software libraries and are deployed on generic hardware, which suffer from delay faults that can cause serious damage. To improve avail ...

Challenges of Memory Management on Modern NUMA Systems

Baptiste Joseph Eustache Lepers, Mohammad Dashti Rahmat Abadi

The latency of memory access times is hence non-uniform, because it depends on where the request originates and where it is destined to go. Such systems are referred to as nonuniform memory access (or NUMA). Current x86 NUMA systems are cache coherent (cal ...

Implementing Virtual Machine Replication: A Case Study using Xen and KVM

André Schiper, Darko Petrovic

Virtual machine (VM) replication has been recognized as an inexpensive way of providing high availability on commodity hardware. Unfortunately, its impact on system performance is far from negligible and strategies have been proposed to mitigate this probl ...

Full System Simulation of Many-Core Heterogeneous SoCs using GPU and QEMU Semihosting

David Atienza Alonso, Luca Benini, Martino Ruggiero, Shivani Raghav

Modern system-on-chips are evolving towards complex and heterogeneous platforms with general-purpose processors coupled with massively parallel manycore accelerator fabrics (e.g. embedded GPUs). Platform developers are looking for efficient full-system sim ...
