Abstract: File-backed virtual disk storage is one of the most important parts of virtualization. In order to enhance the efficiency of virtual disk I/O，this paper researched the file-backed disk virtualization on Xen，analysed using asynchronous I/O method to improve I/O rate，and compared the pros and cons of using different format of virtual disk files as storage device of virtual machines.
Key words: storage virtualization, virtual disk image, Xen
