Hi all, This patch adds a block driver for Sheepdog distributed storage system. Please consider for inclusion. Sheepdog is a distributed storage system for QEMU. It provides highly available block level storage volumes to VMs like Amazon EBS. Sheepdog features are: - No node in the cluster is special (no metadata node, no control node, etc) - Linear scalability in performance and capacity - No single point of failure - Autonomous management (zero configuration) - Useful volume management support such as snapshot and cloning - Thin provisioning - Autonomous load balancing The more details are available at the project site [1] and my previous post about sheepdog [2]. We have implemented the essential part of sheepdog features, and believe the API between Sheepdog and QEMU is finalized. Any comments or suggestions would be greatly appreciated. Here are examples: $ qemu-img create -f sheepdog vol1 256G # create images $ qemu --drive format=sheepdog,file=vol1 # start up a VM $ qemu-img snapshot -c name sheepdog:vol1 # create a snapshot $ qemu-img snapshot -l sheepdog:vol1 # list snapshots ID TAG VM SIZE DATE VM CLOCK 1 0 2010-05-06 02:29:29 00:00:00.000 2 0 2010-05-06 02:29:55 00:00:00.000 $ qemu --drive format=sheepdog,file=vol1:1 # start up from a snapshot $ qemu-img create -b sheepdog:vol1:1 -f sheepdog vol2 # clone images Thanks, Kazutaka [1] http://www.osrg.net/sheepdog/ [2] http://lists.nongnu.org/archive/html/qemu-devel/2009-10/msg01773.html MORITA Kazutaka (2): close all the block drivers before the qemu process exits block: add sheepdog driver for distributed storage support Makefile | 2 +- block.c | 14 +- block.h | 1 + block/sheepdog.c | 1828 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ monitor.c | 1 + vl.c | 1 + 6 files changed, 1845 insertions(+), 2 deletions(-) create mode 100644 block/sheepdog.c -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
