[Qemu-devel] [RFC PATCH v2 0/3] Sheepdog: distributed storage system for QEMU

[MORITA Kazutaka]

Hi all,

This patch adds a block driver for Sheepdog distributed storage
system.

Changes from v1 to v2 are:

 - rebase onto git://repo.or.cz/qemu/kevin.git block
 - modify the sheepdog driver as a protocol driver
 - add new patch to call the snapshot handler of the protocol

One issue still remains; qemu-img parses command line options with
`create_options' of the format handler, so we cannot use protocol
specific options.

In this version, sheepdog needs to be used as a format driver when we
want to use sheepdog specific options.

e.g. Create clone image vol2 from vol1

  $ qemu-img create -b sheepdog:vol1:1 -f sheepdog vol2


Thanks,

Kazutaka
