Determining how many virtual machines a Linux host could run can be a challenge. One of tough missions is to find the balance among performance, density and usability. Now KVM hypervisor has become the most popular open source full virtualization solution. It supports several ways of running guests with more memory than host really has. Due to large differences between minimum and maximum guest...

This paper takes a tour of Virtual Machine Migration systems across physical servers in datacenter which includes it’s architecture, basic working, migration strategies, design issues and goals. Despite of various on-going research for more than two decade in this field, variations in migrations procedures, context, environment and needs is still a major challenge faced by it. Keywords— Virtual...

In traditional data center numbers of services are run onto the dedicated physical servers. Most of the time, these data centers are not used their full capacity in term of resources. Virtualization allows the movement of VM from one host to the another host ,which is called virtual machine migration, so these data centers can consolidate their services onto lesser number of physical servers th...

of thesis entitled “Distributed Java Virtual Machine with Thread Migration” submitted by Wenzhang Zhu for the degree of Doctor of Philosophy at the University of Hong Kong in August 2004 Recent advances in better Java class libraries and Just-in-Time (JIT) compilation techniques have greatly improved the performance of Java to match that of C/C++. To fully exploit Java’s multithreading feature ...

Load balance mechanism does the vital role in high performance computing (HPC) and energy efficient computing (EEC). An effective load balance mechanism achieves high performance resource management. Several load management platform (e.g. Openstack, Nebula and Eucaluptus) available to simulate/perform status of algorithm. Load balance manager should be able to customize the resource management ...

Virtualization technology brings great conveniences to cluster and data center management. By using this technique, we can reconstruct a new computing environment quickly and easily. Compared to the traditional cluster environment, load balancing in a virtualized environment needs to address several new problems. This paper focuses on live migration strategies for load balancing in the virtuali...

Vehicular ad-hoc networks have gained a significant attention during the last decades from the industry and academia with the goals of increasing road safety and traffic management among others. However, vehicles are normally constrained by resources, including computation, storage, and radio spectrum bandwidth. Many emerging applications demand complex computation and large storage, including ...

Nowadays, there are lots of problems in Cloud data center such as high energy consumption and low efficiency. We model a cloud environment with physical hosts and virtual machines, and design an Energy-Aware Virtual Machine Scheduling strategy (EAVMS) to reduce energy consumption and improve utilization rate by integrating system resource such as computing, storage and bandwidth resources. Expe...

Cloud computing provides the opportunity to migrate virtual machines to “follow-the-green” data centres. That is, to migrate virtual machines between green data centres on the basis of clean energy availability, to mitigate the environmental impact of carbon footprint emissions and energy consumption. The virtual machine migration problem can be modelled to maximize the utility of computing res...

Preface This work is a continuation of the NomadBIOS project, where Asger Jensen and I designed and built what would now be termed a para-virtualized hypervisor for hosting multiple virtual machines on top of the L4 microkernel, and—to our knowledge—were the first to show the feasibility of live migration of virtual machines across a local network. Focusing on grid computing, our idea was to pa...
