Aiming at data center virtual machines Migration, allocating resource dynamically in order to reduce energy is a significant problem in cloud. This energy doesn’t cause only the decrease of cloud provider’s profit but also emit a large amount of carbon dioxide. This paper studies the resource allocation and live migration of Virtual Machines (VMs). It proposes a Double Threshold Migration (DTM)...

Vertical elasticity, or scale-up of individual virtual machines is hard to perform in today’s cloud environments due to limitations in the amount of hardware resources available in single servers. We propose a novel approach that allows aggregation of memory, compute and I/O resources from multiple physical machines in resource pools which in turn are used to seamlessly provision virtual machin...

Virtualization plays a very vital role in the big cloud federation. Live and Real-time virtual machine migration is always a challenging task in virtualized environment, different approaches, techniques and models have already been presented and implemented by many researchers. The aim of this work is to investigate various parameters of Real-time and live data migration of virtual machines in ...

Live Migration is one of the essential operations that require more attention to addressing its high variability problems with virtual machines. We review the existing techniques of resource management to find that there are less modeling to solve this problem. The present paper introduces a novel framework that mainly targets to achieve a computational effective resource management technique. ...

The aim of this paper is to improve the performance of network communication between some Virtual Machines in LAN by modifying a script in Xen. Also in this paper we have tested the utilization of CPU and Memory during the live migration phase. After these tests we have concluded that there is no dependency between Memory of Virtual Machines and CPU Consumed. These experiments are performed in ...

This paper addresses the issue of how to meet the strict timing constraints of (soft) real-time virtualized applications while the Virtual Machine (VM) hosting them is undergoing a live migration. To this purpose, it is essential that the resource requirements of a migration are identified in advance, that appropriate resources are reserved to the process, and that multiple VMs sharing the same...
