碩士 === 中華大學 === 資訊工程學系 === 104 === A key function is the live migration in cloud computing, it can enhance the set up and management of virtual machines. For businesses, they need a lot of virtual machines to work in large-scale computing, but the current study, the majority concentrated in a single virtual machine to do research, which means that for the virtual cluster technology to do live migration is inadequate. Therefore, this paper is to discuss Live migration of virtual cluster; live migration of virtual cluster on can easily cause some of the same page repeatedly transmitted or dirty Page, this will make the network overhead becomes large, So we use a hash function to confirm whether the transmission, using NAS to store all the pages in a virtual cluster, if a page has been transmitted only need to send ID number, and then send this page from the NAS. This approach is in order to reduce duplication transmit the same page in a virtual cluster, the network overhead is reduced. The experimental results using the method proposed in this paper can reduce network overhead.
