Research and Implementation of Resource Management System Based on Xen Virtual Machine

With the development of computer technology, there is gradually abundant resource available for computer systems. Virtualization technology provides a viable solution for effective management and rational allocation of system resources. Xen virtual machine is an excellent open source virtual machine, so attracting widespread attention, with broad application prospects. However, the traditional resource management of Xen virtual machine focuses on sharing processor resources fairly, while ignoring the effect of the virtual machines with the different priorities. This would cause the practicality and the performance issues in using virtual machine. This paper proposes a resource management system model based on Xen virtual machine. The model monitors guest domain and analyzes runtime information for automating resource allocation. It mainly take into account the virtual machines with different priorities. Through a series of comparative tests, the results verify that this model can enhance practicality.
