A virtual cluster consists of a multitude of virtual machines and software components that are doomed to fail eventually. In many environments, such failures can result in unanticipated, potentially devastating failure behavior and in service unavailability. The ability of failover is essential to the virtual cluster's availability, reliability, and manageability. Most of the existing methods have...
With the popularity of virtualization, the problem that how to manage hundreds even thousands of virtual machines running on multiple physical computing nodes becomes important. Current virtual machine management systems only can obtain basic information of virtual machines and execute simple operations on them, such as start, reboot and shutdown. In this paper, we design a virtual machine management...
In multi-VM (virtual machine) environment, the virtual machine network management plays an important role. Traditional multi-VM management systems are accustomed to using the DHCP mechanism. However, with the development of virtual network technology, DHCP is not suitable for constructing the stable and transparent virtual network environment. In this paper, we propose a method of multi-VM automatic...
Live migration of virtual machines has been a powerful tool to facilitate system maintenance, load balancing, fault tolerance, and power-saving, especially in clusters or data centers. Although pre-copy is a predominantly used approach in the state of the art, it is difficult to provide quick migration with low network overhead, due to a great amount of transferred data during migration, leading to...
With the development of virtualization technology, it??s desirable to deploy virtual machines to high performance clusters used for data centers. VNIX, developed in Services Computing Technology and System lab, tries to help cluster administrators to manage a large number of virtual machines (VMs) distributed on clusters. To reduce the complexity of virtualization management, VNIX provides a whole-set...
Virtualization technology has provided an opportunity to the efficient usage of computing resources. However, the management of VMs on cluster is still in the preliminary stage. How to construct userpsilas task environments fastly and efficiently remains a significant challenge. This paper presents a multiple-VM deployment system (MVDS) for creating and configuring userspsila task environments on-demand...
Virtualization technology has attracted much attention in recent years. This paper describes the vision and mission of ChinaV, which is the national fundamental research program for virtualization technology in China. Furthermore, related topics about single host virtualization, multiple VM management schemes and desktop virtualization will be introduced. We first describe a remote memory virtualization...
In recent years, virtualization technology has been widely applied to traditional computing environment. As it provides strong flexibility, the security in face of attacks to network services becomes a significant challenge. In this paper, we propose a novel architecture to detect intrusion in virtual computing environment and implement a prototype, named VNIDS. In this system, a particular VM is...
Many grid middleware such as Globus Toolkit and GPE have started to support virtual machines. They implement the remote control of virtual machine by grid service and make use of virtual machinespsila function of quick deployment to construct the execution environment of grid application fast. In order to support virtual machine in grid environment, VMGrid (Virtual Machine Grid) is presented. All...
