Network virtualization: a hypervisor for the Internet?

IEEE Communications Magazine, 2012
Network virtualization is a relatively new research topic. A number of articles propose that certain benefits can be realized by virtualizing links between network elements as well as adding virtualization on intermediate network elements. In this article we argue that network virtualization may bring nothing new in terms of technical capabilities and ...

Seamless Update of a Hypervisor Stack

2021
For security, performance, and competitive reasons, the hypervisor must be regularly updated in order to maintain the cloud infrastructure. This work provides an overview of three novel techniques of updating a hypervisor stack with a minimal disruption for the running virtual machines.

Language-Based Hypervisors

2016
We describe how to build a Language-Based Hypervisor (LBH) that can run untrusted applications (or modules) inside secure containers within a single language runtime instance. The LBH allows execution of untrusted code at a fine-grained level while controlling access to APIs, data, and resources.

Hypervisor-based background encryption

Proceedings of the 27th Annual ACM Symposium on Applied Computing, 2012
To prevent data breaches, many organizations deploy full disk encryption to their computers. While OS-based encryption is widely accepted in practical situations, hypervisor-based encryption offers significant advantages such as OS independence and providing more secure environments.

Enabling power-awareness for the Xen hypervisor [PDF]

ACM SIGBED Review, 2018
Virtualization allows simultaneous execution of multi-tenant workloads on the same platform, either a server or an embedded system. Unfortunately, it is non-trivial to attribute hardware events to multiple virtual tenants, as some system's metrics relate to the whole system (e.g., RAPL energy counters).

Internet of the Body and Cognitive Hypervisor

2017 IEEE/ACM International Conference on Connected Health: Applications, Systems and Engineering Technologies (CHASE), 2017
Wearables that continuously acquire medically relevant parameters can reduce duration of hospitalizations and derive treatment optimizations for individual patients thus improving the quality of medical treatments. We demonstrate an architecture that includes wearables, edge and cloud computing to provide optimal user interaction and analytics of multi-

GPUvm: GPU Virtualization at the Hypervisor

IEEE Transactions on Computers, 2016
Graphic processing units (GPUs) provide a massively-parallel computational power and encourage the use of general-purpose computing on GPUs (GPGPU). The distinguished design of discrete GPUs helps them to provide the high throughput, scalability, and energy efficiency needed for GPGPU applications.

Validating the Microsoft Hypervisor

2006
Efforts to validate the Microsoft Hypervisor – a low-level program that partitions a real MP machine into a a number of virtual MP pachines – has led to some interesting formal methods developments. We'll survey some of these, including – new algorithms for “optimal” stateless search and symbolic stateless search; – techniques to make stateless ...

CrashOS: Hypervisor Testing Tool

2017 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW), 2017
Hypervisors are software more and more widespread because of the increasing usage of virtualization, especially in the Cloud. But they are not bug-free. CrashOS is developed to test them and contributes to find security vulnerabilities in hypervisors.
