Abstract


With the rapid development and wide application of computer technology and network technology, sharing and comprehensive utilization of network resources is becoming more and more urgent. In this context, network computing technology rapid development, its goal is the wide-area distributed, heterogeneous computing resources, storage resources, information resources and equipment resources and other resources together, through the collaborative sharing across autonomous domains and synergy, integration of resources and to provide users with information services platform to meet the needs of increasingly complex applications for large-scale computing power, massive data processing, and a variety of information services. Virtual machine technology has transparency, isolation, encapsulation and manageability features, virtual machine technology and network computing technology combined by the ability to easily create, use, and remote management of the virtual machine and efficient sharing of network resources, and build support a variety of complex applications, and can be customized network computing environment. This paper designs and implements a virtual machine-based distributed virtual operating environment DVEE system, create remote virtual machine deployment, monitoring and management capabilities, effective aggregation and sharing networks in a variety of widely distributed heterogeneous and autonomous resources, provide for a variety of users and applications can be customized, and dynamically build the virtual application runtime environment. The main work of this paper include: (1) design the distributed virtual operating environment DVEE the model using XML Schema to describe the model. The system supports user-written meet DVEE model Schema specification XML file describing the required application runtime environment for each virtual machine node soft, hardware configuration information and inter-node network topology, DVEE responsible for parsing the XML file and automatically deploy virtual machines in the network , to build a virtual operating environment: (2) to achieve effective control and management of remote virtual machines to support the user to effectively manipulate the virtual machine distribution network through the graphical interface of the browser, easy to use DVEE for a variety of different types of distributed applications to build a virtual operating environment; (3) Find a user needs, the algorithm considering the service capabilities of resource owners and the dynamic load matching algorithm VMADA remote virtual machine to virtual machine resource allocation and scheduling, promote the DVEE system load balancing and performance optimization; (4) according to the distributed virtual operating environment DVEE model and system architecture design, to achieve a DVEE prototype system.
