[Qemu-devel] [PATCH] HLFS driver for QEMU

2013-03-17 Thread harryxiyou
From: Harry Wei HLFS is HDFS-based(Hadoop Distributed File System) Log-Structured File System. Actually, HLFS, currently, is not a FS but a block-storage system, which we simplify LFS to fit block-level storage. So you could also call HLFS as HLBS (HDFS-based Log-Structured Block-storage System).
