摘要
首先对虚拟机在迁移过程中，内存脏页面产生数量与不同应用特征的密切关系进行了实验验证。在感知不同的虚拟机应用特征环境的基础上，使用GM(1
N)灰色预测模型对每次迭代周期产生的内存脏页面数进行预测。同时使用残差修正进行误差调整，使预测结果更可靠，结合预测的内存脏页面数量进行网络带宽动态预留调整。实验表明：与传统的pre-copy策略相比，本方法在含网络密集型应用或内存密集应用的虚拟机迁移时，能够有效提高网络性能，降低迁移时间。
Abstract
Firstly the experiments to verify the relationship between the number of dirty memory pages and application characteristics which exist in virtual machine migration was conducted.Then
different virtual machine application characteristics were perceived
with which the number of dirty memory pages produced during the migrations was predicted by the use of GM(1
N) grey prediction model.At the same time
using residual correction to adjust error makes results more reliable.According to the prediction of memory dirty pages
network bandwidth was adjusted and reserved.Compared with the traditional pre-copy strategy
the given experiments show that the optimized strategy proposed can improve the performance of network and reduce migratory cost for the memory-intensive and network-intensive applications.
