Live Migration of Virtual Block Devices
نویسندگان
چکیده
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 and without sacrificing I/O performance. Our initial implementation shows that migrating virtual block devices is feasable and can occur with unnoticeble downtime. The advantage of using live migration for user mobility that the work environment is never suspended and that network connections are not disturbed and batch jobs can be executed during user’s commutes.

Analytical evaluation of an innovative decision-making algorithm for VM live migration
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...
متن کاملA Versioning Approach to VM Live Migration
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...
متن کاملLive Migration of User Environments Across Wide Area Networks
A complex challenge in mobile computing is to allow the user to migrate her highly customised environment while moving to a different location and to continue work without interruption. I motivate why this is a highly desirable capability and conduct a survey of the current approaches towards this goal and explain their limitations. I then propose a new architecture to support user mobility by ...
متن کاملA Near Optimal Approach in Choosing The Appropriate Physical Machines for Live Virtual Machines Migration in Cloud Computing
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...
متن کاملA version numbering scheme for informational objects used in VM live migration
Various numbering schemes are used to track different versions and revisions of files, software packages, and documents. One major challenge in this regard is the lack of an all-purpose, adaptive, comprehensive and efficient standard. To resolve the challenge, this article presents Quadruple Adaptive Version Numbering Scheme. In the proposed scheme, the version identifier consists of four integ...
