Abstract

A management model of virtual machines was proposed based on Peer-to-Peer(P2P) structure and its prototype system was implemented.Host nodes were organized in P2P structure and resource discovery was achieved by multicast.Live migration algorithm of virtual machines was proposed and live migrations between nodes were automatically triggered.The requests of cloud computing user were mapped to the host by elected root node,and the on-demand operations of creating,deleting,and stopping a virtual machine were achieved.The experimental results show that: the model has the features of rapid convergence,low bandwidth utilization and high availability.Load balance of cloud computing resources can be achieved.
