A Flexible Multi-layered Virtual Machine Design for Virtual Laboratories in Grid Systems
نویسندگان
چکیده
We propose a flexible Multi-layered Virtual Machine (MVM) design intended to improve efficiencies in grid computing and to overcome known problems that exist in grid systems. We present a novel approach to building virtual laboratories by adapting MVMs within distributed and grid systems, thereby providing enhanced flexibility and reconfigurability. The MVM is a service-oriented grid architecture to discover, describe and retrieve platform independent configuration models for each resource usage pattern and provides virtual laboratory users with a logical view of the grid. It consists of three layers: OS-level, Queuelevel, and Component-level VMs. MVMs virtualize system resources, topologies, networks, policies and services. In our framework, the virtual machines can be created “on-demand” and their applications can be distributed at the source-code level, compiled and instantiated in run-time. Key-Words: Multi-layered Virtual Machine, Grids, Service-Oriented Architecture
