Abstract: With the development and popularization of cloud computing technology, desktop virtualization technology has also been fully developed and applied. The speed of library digital construction is also accelerating, and library retrieval terminals have encountered problems such as management difficulties and high maintenance costs. This paper first analyzes the current situation of virtualization technology application at home and abroad and the construction status of library virtualization system, and summarizes the advantages and disadvantages of library virtualization system at home and abroad. Based on this, the Tsinghua University Library is used as a prototype. Desktop virtualization technology is used to design and realize the informatization construction of the library. The main research contents of the thesis are summarized as follows:[Objective] Study the application of virtualization of libraries in various universities in China, and find out the solutions to problems encountered in the construction of library information.[Methods] Based on computer virtualization technology, it mainly analyzes the implementation of desktop virtualization.[Conclusions] Through desktop virtualization technology, Tsinghua University Library has enhanced the scalability and security of the search terminal desktop system, improved hardware utilization, and obtained the conclusion that using desktop virtualization technology is good to facilitate resource storage and management and reduce operating costs.
