The virtual machine migration is core feature of virtualization that plays important role in cloud computing. The resource utilization is monitored by local migration agent that launches migration of virtual machine from one physical machine to another. Various virtual machine migration techniques are explored for efficient utilization of resources. With rapid increase in data centers, it becom...

Live virtual machine migration is a powerful tool offered by virtualization technologies. However, current implementations restrict its usage to local area networks. Extensions to wide-area networks have been proposed with systems for transferring disk state and transparently migrating network connections. Still, wide-area live migration remains expensive to use because of the bandwidth bottlen...

Cluster platforms, deployed in data centers worldwide, are the backbone of the popular cloud computing services. For scalability, manageability and resource utilization, one physical machine in the cloud platform can be virtualized into a bundle of virtual machines (VMs). Each VM works as an independent node. To solve a time consuming task, several VMs are grouped as a virtual cluster and colla...

Virtual machine (VM) live migration, which is the ability to move a VM from one physical host to another under hypervisor control without suspending for a long time, is a capability being increasingly utilized. With IP mobility, a capability for migrating VMs among distributed sites is provided. We call it the global live migration. However, it affects an application program on a VM compared wi...

The concept of network virtualization, such as network functions virtualization, has attracted considerable attention from telecom carriers and a live migration technique is a key feature of virtualization technology. However, there are some challenges associated with applying server virtualization technology including live migration to a SIP server. Previous work has not dealt with the perform...

In the virtualization technique, numbers of different components are involved to manage the network, storage, memory. Live migration is the key concept in which the live or active virtual machine is migrated from one host to another host i.e. physical server without disturbing the live environment and the services. This feature is useful for handling the different tasks like power management, I...

Virtual Machines need migration from the present host to an another appropriate one due to error in the present hardware or presently loaded scenario causing slowness of execution. Most of the situations fall into second category leading to a solution called live migration. Here, in live migration the virtual machine runs for sometime on the present host while its required data gets transferred...
