Research On Virtual Machine Migration Integrity Metrics Based On Trusted Computing

In the era of digital age,by the many servers constitute a cloud computing data center,the physical server load higher or lower,will affect the efficiency of the entire system.In order to achieve the entire architecture of the load balance,you need to use the virtual machine’s dynamic online migration technology.Including the operating system,including the entire system operating environment Virtual machine dynamic online migration technology to migrate from the source host to the destination host,a better solution to the physical machine resource management and monitoring issues,thus making the server load balance,improve the resources The use of efficiency and quality of service,effectively reducing energy consumption.Therefore,how to solve the problem of virtual machine online migration has become the key to the current research.In this paper,we analyze the migration performance of virtual machine in different dirty page rate environment,and propose an effective method to improve the performance and verify the migration security.The research results are as follows:(1)In the virtual machine migration process,due to various reasons downtime and the total migration time is too long,not only increase the system burden,while affecting the stability of the migration.In this paper,based on the memory pre-copy migration algorithm,according to the characteristics of dirty dirty pages,calculate the dirty page rate,re-order dirty pages,combined with efficient compression method for compressed transmission,thereby enhancing the virtual machine migration performance.(2)In order to ensure the integrity of online migration,this paper based on the trusted computing module provides a complete credible measurement,storage measures,and build a complete trusted chain,remote verification for migration provides a platform guarantee.(3)Through the experiment of designing different dirty page rate environment,the practicality of the algorithm under different environment is analyzed.At the same time,a trusted platform is built,which guarantees the integrity of virtual machine migration and improves the security performance of virtual machine migration.
