Abstract:
Using a simple library operating system (OS) as a guest OS of a virtualized environment is one of the current trends of cloud computing in order to reduce the overheads incurred by virtualization. Its persistent storage access, however, remains the same as that for the existing guest OSes; thus, it poses a problem of the long execution and data paths. This paper proposes virtualized memory storage that provides the memory interface for a library OS of a virtualized environment, and also discusses the two key benefits of virtualized memory storage, journaling acceleration by synchronous access and a modern implementation of single-level store. The proposed memory interface to virtualized memory storage can simplify both of the execution and data paths, and it accelerates the access to persistent storage.
