Yang Gui-fei Seen by Her Contemporaries : Mainly on the Device of Comparison in the Poems of Li Bai and Du Fu
No full textSince the Heian period, Yang Gui-fei has been regarded by the Japanese people with considerable favor as a woman of peerless beauty and a heroine of the tragic romance with Xuan-zong Huang-di 玄宗皇帝. This tendency goes beyond the fields of literature and entertainment. In its extreme, the admiration for beautiful Yang Gui-fei has even made her an object of worship as a Bosatsu or Kan-non. In China, however, Yang Gui-fei generally does not seem to have been very popular with the public. This was certainly true in the Tang 唐 dynasty when she lived. The purpose of this paper is to examine, through the study of the poems of Li Bai and Du Fu, what kind of figure Yang Gui-fei cut among her contemporaries. The most noticeable aspect of the poems on Yang Gui-fei is that both of these poets compare her to Zhao Fei-yan 趙飛燕 and Xi Wang-mu 西王母, celebrated beauties who enthralled their emperors. Yet there have been many other women figures, both historical and mythic, who were beautiful and famous for their romance with emperors; why did the poets choose these two specific women as the historicalmythic counterparts of Yang Gui-fei? The answer lies in the duplicity of their characters. Both of these women were physically beautiful, but spiritually they were ugly and corrupt. By likening Yang Gui-fei to these two women, therefore, Li Bai and Du Fu intended implicitly to criticize her ugly mind, while on the surface they admired her beauty. What struck the poets as ugly in these women was, in short, their seductive and lewd character. By their ingenious comparisons, the poems of Li Bai and Du Fu hint and satirize that Yang Gui-fei, utilizing this unsavory character, captivated the emperor, gained control of political power, and thus exerted a destructive influence on government administration. Such a satiric approach began with Li Bai, and was taken over by Du Fu. Li Bai's view of Yang Gui-fei was based on his own experiences in the Court. So it may be safe to believe that, in his association with Li Bai, Du Fu learned not only the poetics, but also the court experiences, of Li Bai
LayerMover: Storage Migration of Virtual Machine across Data Centers Based on Three-Layer Image Structure
No full textLayerMover: Fast Virtual Machine Migration over WAN with Three-Layer Image Structure
No full textLive Virtual Machine (VM) migration across data centers is an important technology to facilitate cloud management and deepen the cooperation between cloud providers. Without the support of a shared storage system between data centers, migrating the storage data (i.e. virtual disk) of a VM becomes the bottleneck of live VM migration over Wide Area Network (WAN) due to the contradiction between the low bandwidth of the Internet and the comparatively large size of VM storage data. According to previous studies, many inter- and intra-VM duplicated blocks exist between VM disk images. Therefore, data deduplication is widely used for accelerating VM storage data migration. However, it must make a trade-off between computation cost and transmission benefit. Existing approaches are fragile as they explore only the static data feature of image files without much consideration on data semantics. They may adversely influence on migration performance when the benefit resulting from data deduplication cannot remedy its computation overhead. In this paper, we propose a new space-efficient VM image structure—three-layer structure. According to different functions and features, the data of a VM are separated into an Operating System (OS) layer, a Working Environment (WE) layer, and a User Data (UD) layer. Based on this structure, we design a novel VM migration system—LayerMover. It mainly focuses on improving migration performance through optimizing the data deduplication technique. Our experimental results show that three-layer image structure can improve data sharing between VMs, and the similarity ratio between WE images can reach 70%. The tests for LayerMover indicate that it can be significantly beneficial to VM migration across data centers, especially when multiple VMs which share base images are migrated

CBase: a new paradigm for fast virtual machine migration across data centers
No full textLive Virtual Machine (VM) migration offers a couple of benefits to cloud providers and users, but it is limited within a data center. With the development of cloud computing and the cooperation between data centers, live VM migration is also desired across data centers. Based on a detailed analysis of VM deployment models and the nature of VM image data, we design and implement a new migration framework called CBase. The key concept of CBase is a newly introduced central base image repository for reliable and efficient data sharing between VMs and data centers. With this central base image repository, live VM migration and further performance optimizations are made possible. The results from an extensive experiment show that CBase is able to support VM migration efficiently, outperforming existing solutions in terms of total migration time and network traffic
