Hosting virtual servers on a shared physical hardware by means of hardware virtualization is common use at data centers, web hosters, and research facilities. All virtualization platforms include isolation techniques that restrict resource consumption of the virtual guest systems. Therefore, they setup quotas for the virtual guest systems on the use of processors, memory, and hard disk of the h...

Server virtualization has brought about tremendous value to a modern computing landscape and in particular to data center and cloud infrastructures. Virtual server deployments have become ubiquitous in many development and production sites, in cloud infrastructures and in disaster recovery solutions. Network connectivity is a vital aspect of modern computing. In this work we explore the new req...

Personal computers have diverse and fast-evolving I/O devices, making their I/O virtualization different from that of servers and data centers. In this paper, we present our recent endeavors in simplifying I/O virtualization for personal computers. Our key insight is that many operating systems, including Unix-like ones, abstract I/O devices as device files. There is a small and stable set of o...

Today's technical news is filled with stories of server and desktop virtualization, but there's another virtualization technology that's growing rapidly: embedded virtualization. The embedded domain has several useful applications for virtualization, including mobile handsets, security kernels, and concurrent embedded operating systems. This article explores the area of embedded virtualization ...

Virtualized data center infrastructures demand a solid foundation that delivers scale, resilience, flexibility and efficiency. Hitachi and Cisco, today’s leading advocates of data center infrastructure virtualization, have teamed to develop a blueprint for large-scale data center virtualization that satisfies these demands. Hitachi Unified Compute Platform (UCP) Select for VMware vSphere with C...

Over the past several years, virtualization has been a hot topic of much discussion by IT personnel as a way to reduce cost, improve utilization and responsiveness, and increase flexibility. Although server consolidation still remains the primary reason for using virtualization, application isolation and continuity are also discussed as other uses. This paper presents three use cases for deploy...

One of the activities of the Pacific Rim Applications and Grid Middleware Assembly (PRAGMA) is fostering Virtual Biodiversity Expeditions (VBEs) by bringing domain scientists and cyber infrastructure specialists together as a team. Over the past few years PRAGMA members have been collaborating on virtualizing the Lifemapper software. Virtualization and cloud computing have introduced great flex...

Network virtualization is a concept where physical resources are used to create virtual resources that are combined to form virtual networks. As one of the key enablers of the future Internet, network virtualization solves a number of issues associated with today’s networks. Concepts of network virtualization that are not restricted to virtualization technology, termed as overall concepts that ...
