Virtualization has become commonplace in modern data centers, often referred as “computing clouds”. The capability of virtual machine live migration brings benefits such as improved performance, manageability and fault tolerance, while allowing workload movement with a short service downtime. However, service levels of applications are likely to be negatively affected during a live migration. F...

The Physical servers used in IT are under-utilized. The better utilization of these servers can be achieved using virtualization technology. Virtualization techniques create multiple partitions which are isolated with each other called virtual machines. Each virtual machine (guest) runs their own operating system. The resource allocated for these VMs may fail to execute an application because o...

Live migration enables a running virtual machine to move between two physical hosts with no perceptible interruption in service. This allows customers to avoid costly downtimes associated with hardware maintenance and upgrades, and facilitates automated load-balancing. Consequently, it has become a critical feature of enterprise class virtual infrastructure. In the past, live migration only mov...

Today’s computing environments do not provide support for seamless user mobility. We argue that the support for user mobility between various computing environments can be improved by using live migration of virtual machines and present our initial steps in this direction. We are addressing efficient live migration of persistent storage without leaving residual depencies between migration sites...

When users flood in cloud data centers, how to efficiently manage hardware resources and Virtual Machines (VMs) in a data center to both lower economical cost and ensure a high service quality becomes an inevitable work for cloud providers. VM migration is a cornerstone technology for the majority of cloud management tasks. It frees a VM from the underlying hardware. This feature brings a plent...

Virtualization technology plays a great role in cloud computing. Virtualization supports creation and migration of virtual machines (VM) on physical hosts. Live migration provides the load balancing of virtual machine. One of the objectives of live migration is that it should have minimum migration time as well as downtime so that application running on VM will be suspended for negligible time....

Virtualization technology reduces cloud operational cost by increasing cloud resource utilization level. The incorporation of virtualization within cloud data centers can severely degrade cloud performance if not properly managed. Virtual machine (VM) migration is a method that assists cloud service providers to efficiently manage cloud resources while eliminating the need of human supervision....
