根据云计算平台的特点,提出一种新型虚拟机动态迁移框架,并在Xen和KVM这2种典型的开源虚拟机监控器基础上,实现原型系统。测试结果表明,在不同类型计算资源的环境下,该动态迁移框架具有良好的性能,能够对动态迁移进行实时控制,从而满足服务等级协议的要求。
Considering the features of cloud computing, a new live virtual machine migration framework is presented. It is implemented on basis of two typical open source Virtual Machine Monitor(VMM) Xen and KVM. Test results show this framework has good performance, which can dynamically control the migration process to meet Service Level Agreement(SLA).
