摘要: Efficiently managing storage is important for virtualized computing environments. Its importance magnified by developments such as cloud which consolidate many thousands of virtual machines (and their associated storage). The nature this that there a large amount duplication between otherwise discreet machines. Building upon previous work in content addressable storage, we have built prototype consolidating disk images using service-oriented file system. It provides hierarchical organization, manages historical snapshots drive images, and takes steps to optimize encoding based on partition type In paper present our experiences with building it store variety QEMU the Linux Kernel Virtual Machine (KVM).
