Green cloud data center has become a research hotspot of virtualized cloud computing architecture. And load balancing has also been one of the most important goals in cloud data centers. Since live virtual machine (VM) migration technology is widely used and studied in cloud computing, we have focused on location selection (migration policy) of live VM migration for power saving and load balanc...

Migrating a live, running operating system from one machine to another has proven to be an invaluable tool over the past few years. Today, however, the only way to migrate an OS is to run it in virtual machine, thereby incurring the disadvantages of virtualization (e.g., virtualized devices often do not keep pace with the latest hardware). This paper proposes a new infrastructure for operating ...

Virtual services on computation resources like CPUs and storages are supported to applications by using virtual machines in server clusters. Virtual machines with application processes can migrate from host servers to guest servers. In this paper, we discuss a process migration approach to reducing total electric energy consumption of servers by taking advantage of virtual machines in a cluster...

When a network application is implemented as a virtual machine on a cloud and is used by a large number of users, the location of the virtual machine should be selected carefully so that the response time experienced by users is minimized. As the user population moves and/or increases, the virtual machine may need to be migrated to a new location or replicated on many locations over a wide-area...

The Cloud Computing model leverages virtualization of computing resources allowing customers to provision resources on-demand on a pay-as-you-go basis. During recent years, the power consumption of datacenters in cloud environment attracted researchers. Optimization of energy consumption can be performed by different methods including virtual machine (VM) consolidation. This technique can reduc...

Virtualization provides an efficient solution to the objectives of the cloud computing paradigm by facilitating creation of Virtual Machines (VMs) over the underlying physical servers, leading to improved resource utilization and intellection. Virtualization proposes to create a virtual version of a device or a resource likely to virtualize a server, a storage space, operating system or even ne...

Server consolidation of virtual machines is very much essential in a cloud environment for energy conservation and cost cutting . Consolidation can be achieved through live migration of virtual machines. We propose a modified bin packing algorithm for Server Consolidation that avoids unnecessary migrations and minimizes the instantiation of new physical servers. We implement ideas from the Firs...

Implementing and maintaining file systems is painful. OS functionality is notoriously difficult to develop and debug, and file systems are more so than most because of their size and interactions with other OS components. In-kernel file systems must adhere to a large number of internal OS interfaces. Though difficult during initial file system development, these dependencies particularly compli...
