In recent years, there has been a rapid growth in the adoption of virtual machine technology in data centers and cluster environments. This trend towards server virtualization is driven by two main factors: the savings in hardware cost that can be achieved through the use of virtualization, and the increased flexibility in the management of hardware resources in a cluster environment. An import...

Virtualization has now become ubiquitous, especially in large-scale data centers. Significant inroads have also be made into high performance computing and adaptive systems, areas where I have focused in the Virtuoso and V3VEE projects. The rapid adoption of virtualization in all of these areas is in no small part due to the ability of full system virtualization to adapt existing OSes to virtua...

Virtualization technology starts becoming more and more widespread in the embedded systems arena, driven by the upward trend for integrating multiple environments into the same hardware platform. The penalties incurred by standard software-based virtualization, altogether with the strict timing requirements imposed by real-time virtualization are pushing research towards hardware-assisted solut...

Server virtualization influences all aspects of IT service management, and is a key enabling technology for cloud computing. In this paper we focus on the impact of server virtualization on service delivery and service support as described by ITIL. We identify advantages, disadvantages, and risks of server virtualization for capacity, management, availability, costs, and security of IT services...

Network virtualization promises to fulfill the demand for an agile Internet that is friendly to technological innovation. In the past, tremendous effort s have been dedicated to studying the fundamental problem in network virtualization, namely Virtual Network Embedding (VNE). However, until recently, very limited work has addressed the security issues and implications of VNE or network virtual...

Virtualization is a technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. The benefits of virtualization techniques are becoming more and more appealing nowadays where the demand for high quality of service and error free systems is a requirement to every system. A lot of work has been done in the domain of virtual servers but database ...

Network Function Virtualization (NFV) virtualizes software network functions to offer flexibility in their design, management and deployment. Although GPUs have demonstrated their power in significantly accelerating network functions, they have not been effectively integrated into NFV systems for the following reasons. First, GPUs are severely underutilized in NFV systems with existing GPU virt...

In order to meet the requirements of standardization of virtualization in cloud computing platform, improve the flexibility and expansibility of the system and enhance the capability of management-control of the platform, by means of introducing the features of decoupling and semantic of metadata, a Metadata-driven Cloud Computing Application Virtualization Model(MCCAVM) in software level is pr...

It has become the hot research issue that solves the bottleneck of resource management in the development of Internet through virtualization. However, there are the challenges of mobility management, resource management, and network overhead management in the virtualization of the Internet. First, based on the mobile Internet network construction and management mode, the mobile Internet virtual...

Applying System Virtualization to Reuse Software. Hypervisor-based virtualization refers to the division of the resources of a computer system into multiple execution environments in order to share the hardware. Multiple existing software stacks of operating system and applications such as third party components, trusted legacy software, and newly developed application-specific software can be ...
