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...

Migration of Virtual Machine (VM) is a critical challenge in cloud computing. The process to move VMs or applications from one Physical Machine (PM) to another is known as VM migration. In VM migration several issues should be considered. One of the major issues in VM migration problem is selecting an appropriate PM as a destination for a migrating VM. To face this issue, several approaches are...

Application migration and heterogeneity are inherent issues of pervasive systems. Each implementation of a pervasive system must provide its own migration framework which hides heterogeneity of the different resources. This leads to the development of many frameworks that perform the same functionality. We propose a minimal execution environment, the micro virtual machine, that factorizes proce...

A method to migrate a task dynamically from a virtual SPMD machine to a virtual SIMD machine is proposed. It is assumed that the SIMD and SPMD virtual machine models only differ to support the different modes of parallelism, and that the program was coded in a modeindependent programming language. The migration pro­ cedure does not require the SPMD PEs to be at the same location in the SPMD pro...

Past research in virtualisation technology has mainly focused on increasing isolation of co-resident virtual machines. At the same time network intensive applications, such as web services or database applications are being consolidated onto a single physical platform. The isolation properties of virtualisation, however, demand a strict separation of the shared resources. Co-resident virtual ma...

Live migration is commonly employed by cloud providers for performance reasons (e.g., ensuring load balancing). Recently, migration has been considered as a countermeasure against cloud-based side-channel attacks. In this paper, we discover an attack using which an adversary can effectively stall a live migration; this can not only hurt performance but also hurt the usage of virtual machine (VM...

Live VM (virtual machine) migration has become a research hotspot of virtualized cloud computing architecture. We present a novel migration algorithm which is called HMDC. Its main idea includes two parts. One is that it combines memory pulling copy with memory pushing copy to achieve hybrid memory copy. The other one is that it uses a delta compression mechanism during dirty pages copy, in whi...
