In order to achieve the virtual machines live migration, the two "pre-copy" and "post-copy" strategies are presented. Each of these strategies, depending on the operating conditions of the machine, may perform better than the other. In this article, a new algorithm is presented that automatically decides how the virtual machine live migration takes place. In this approach, the virtual machine m...

In the context of virtual machines live migration, two strategies called “pre-copy” and “post-copy” have already been presented; but each of these strategies works well only in some circumstances. In this paper, we have a brief presentation of QAVNS and then introduce a new approach which is based on the concept of "informational object", assigning QAVNS-scheme-revision number, and observing th...

Live migration is an essential feature of virtualization that allows transfer of virtual machine from one physical server to another without interrupting the services running in virtual machine. Live migration facilitates workload balancing, fault tolerance, online system maintenance, consolidation of virtual machines etc. Unfortunately the disclosed vulnerabilities with the live migration pose...

Virtualization technology is currently becoming increasingly popular and valuable in cloud computing environments due to the benefits of server consolidation, live migration, and resource isolation. Live virtual machine migration is the process of moving virtual machine from one physical host to other without disturbing the users. Effective migration of virtual machine requires the movement of ...

The live migration of Virtual Machines (VMs) is a key technology in server virtualization solutions used to deploy Infrastructure-as-a-Service (IaaS) clouds. This process, on one hand, increases the elasticity, fault tolerance, and maintainability in the virtual environment. On the other hand, it increases the security challenges in cloud environments, especially when the migration is performed...

Virtual machine live migration in cloud environments aims at reducing energy costs and increasing resource utilization. However, its potential has not been fully explored because of simultaneous migrations that may cause user application performance degradation and network congestion. Research efforts on live migration orchestration policies still mostly rely on system level metrics. This work ...

Cloud computing is a technology that is built on the theory of virtualizationthe idea to allow multiple virtual machines to share the resources of a host. One of the features of virtualization is live migration. This feature will allow one or more virtual machines to be migrated from one host to another without interfering with applications running on those virtual machines. However, there are ...

Romero, Raul F. M.S., Purdue University, August, 2010. Live Migration of Parallel Applications. Major Professor: Thomas J. Hacker. It has been observed on engineering and scientific data centers that the absence of a clear separation between software and hardware can severely affect parallel applications. Applications that run across several nodes tend to be greatly affected because a single co...

For the purpose of load balancing, migration of VM instances or processes in cloud environment is quite useful. However, the live migration of VM is insecure. There is necessity of incorporating encryption and authentication mechanisms during migration process. An attempt is made to secure live migration of virtual machine and running processes from one machine to another. In this system, the v...
