【摘要】：隨著虛擬化技術(shù)的廣泛應(yīng)用,越來(lái)越多的企業(yè)運(yùn)用虛擬機(jī)技術(shù)進(jìn)行系統(tǒng)和服務(wù)器建設(shè),但如何有效的監(jiān)控多個(gè)物理機(jī)和部署在其上的大量虛擬機(jī)成為虛擬機(jī)管理的難點(diǎn)。虛擬器件的提出,雖然解決了傳統(tǒng)企業(yè)信息系統(tǒng)發(fā)布和部署時(shí)環(huán)境兼容性、操作復(fù)雜度高和安全復(fù)雜度高的問(wèn)題,但也給信息系統(tǒng)的部署帶來(lái)了平臺(tái)兼容、虛擬化平臺(tái)兼容和物理體積三方面的局限性,管理員運(yùn)用普通虛擬器件難以高效的管理大規(guī)模虛擬機(jī)。 針對(duì)以上問(wèn)題,本文在對(duì)商用虛擬器件進(jìn)行深入研究的基礎(chǔ)上,提出一種特殊的具有自維護(hù)功能的虛擬器件,稱之為虛擬構(gòu)件。在構(gòu)件的設(shè)計(jì)中加入代理服務(wù)機(jī)制,采用代理服務(wù)機(jī)制的虛擬構(gòu)件能夠獲得虛擬機(jī)內(nèi)部運(yùn)行情況,方便管理員進(jìn)行細(xì)粒度的控制和維護(hù)。 虛擬構(gòu)件代理服務(wù)機(jī)制的主要思想為：通過(guò)在虛擬機(jī)內(nèi)部設(shè)計(jì)代理服務(wù)模塊,建立起虛擬機(jī)與物理機(jī)之間數(shù)據(jù)交互的通道,使得管理員能夠獲得虛擬機(jī)內(nèi)部的數(shù)據(jù),并能進(jìn)行虛擬機(jī)操作管理。同時(shí),代理服務(wù)機(jī)制加入了自維護(hù)規(guī)則集,并在虛擬機(jī)中布置感應(yīng)器與效應(yīng)器,對(duì)于基本的維護(hù),管理員無(wú)需進(jìn)行管理操作,就能實(shí)現(xiàn)自維護(hù)。 為設(shè)計(jì)和實(shí)現(xiàn)上述目標(biāo),本文進(jìn)行了以下幾方面的工作： (1)虛擬構(gòu)件運(yùn)維模型的建立。主要分為虛擬構(gòu)件和虛擬構(gòu)件管理平臺(tái)的設(shè)計(jì)。其中,虛擬構(gòu)件包括虛擬構(gòu)件元信息、維護(hù)規(guī)則集、感應(yīng)器、效應(yīng)器等。虛擬構(gòu)件管理平臺(tái)包括知識(shí)庫(kù)、監(jiān)視器、決策元、執(zhí)行器等。 (2)對(duì)于數(shù)據(jù)傳輸模塊,本文設(shè)計(jì)中加入了最小數(shù)據(jù)傳遞更新算法,確保傳輸數(shù)據(jù)的最小化,優(yōu)化網(wǎng)絡(luò)帶寬,提高傳輸性能。并對(duì)算法進(jìn)行了測(cè)試,實(shí)驗(yàn)結(jié)果表明算法的加入,對(duì)于集群虛擬機(jī)管理能明顯提高效率。 (3)對(duì)虛擬構(gòu)件管理平臺(tái)監(jiān)控模塊進(jìn)行界面開(kāi)發(fā),獲得物理機(jī)和虛擬機(jī)的內(nèi)部數(shù)據(jù),便于管理員查看和管理。對(duì)自維護(hù)功能進(jìn)行了演示程序展示。
[Abstract]:With the wide application of virtualization technology, more and more enterprises use virtual machine technology for system and server construction, but how to effectively monitor multiple physical machines and a large number of virtual machines deployed on them becomes the difficulty of virtual machine management. The introduction of virtual devices solves the problems of environment compatibility, high operation complexity and high security complexity when traditional enterprise information systems are published and deployed, but it also brings platform compatibility to the deployment of information systems. Due to the limitations of virtualization platform compatibility and physical volume, it is difficult for administrators to efficiently manage large virtual machines with common virtual devices. In order to solve the above problems, based on the in-depth study of commercial virtual devices, this paper proposes a special virtual device with self-maintenance function, which is called virtual component. The agent service mechanism is added to the design of the component, and the virtual component using the proxy service mechanism can obtain the internal running situation of the virtual machine, which is convenient for the administrator to control and maintain fine granularity. The main idea of the proxy service mechanism of virtual component is: through designing proxy service module in virtual machine, the channel of data interaction between virtual machine and physical machine is established, so that the administrator can obtain the data inside virtual machine. And can manage the operation of virtual machine. At the same time, the agent service mechanism adds the self-maintenance rule set, and arranges the sensor and the effector in the virtual machine. For the basic maintenance, the administrator can realize the self-maintenance without the need of the management operation. In order to design and achieve the above objectives, this paper has done the following work: 1) Establishment of virtual component operation and maintenance model. It is mainly divided into virtual component and virtual component management platform design. Among them, virtual component includes virtual component meta-information, maintenance rule set, sensor, effector and so on. Virtual component management platform includes knowledge base, monitor, decision element, actuator and so on. For the data transmission module, the minimum data transfer update algorithm is added in this paper to ensure the minimum data transmission, optimize the network bandwidth, and improve the transmission performance. The experimental results show that the addition of the algorithm can improve the efficiency of cluster virtual machine management. The interface of monitoring module of virtual component management platform is developed, and the internal data of physical machine and virtual machine are obtained, which is convenient for administrator to view and manage. The function of self-maintenance is demonstrated.
