[Qemu-devel] [PATCH V10 00/13] Quorum block driver

[Benoît Canet]

Here is the new version of the QUORUM block driver.
It now use bdrv_image_open for using QMP references and support snapshotting
via the bs node-name infrastructure.

I think the series is feature complete.

It applies on top of Max bdrv_openv2 branch.
