Cloud computing is one of the most popular Internet concepts, and many large companies provide cloud services to users. These large companies have built their own data centers to support upper layers of cloud services. To save cost and increase flexibility, SDN and virtualization technologies are widely used in data centers. Open vSwitch is an open source virtual switch that supports the OpenFlow...
Virtualization technology has played an increasingly important role in modern datacenters and cloud computing. With the rapid development of hardware, the capability of single physical server has become more and more powerful. So it has been a trend that deploying multiple VMs (Virtual Machines) on a single physical host, which is so called virtual machine consolidation. High degree of VM consolidation...
Live migration of virtual machine (VM) enables mobility of VM and contributes to advantages of virtualization like energy saving, high availability, fault tolerance and work load balancing. However solutions of VMs' migration in both theoretical and industrial areas concentrate more on memory migration other than storage migration. Lots of applications with intensive disk I/O operations rely on local...
Live migration of virtual machine plays an important role in data center, which can successfully migrate virtual machine from one physical machine to another with only slight influence on upper workload. It can be used to facilitate hardware maintenance, load balancing, fault-tolerance and power-saving, especially in cloud computing data centers. Although the pre-copy is the prevailing approach, it...
