[Qemu-block] [PATCH 0/5] Promote x-nbd-server-add-bitmap to stable

Subject: [Qemu-block] [PATCH 0/5] Promote x-nbd-server-add-bitmap to stable
Date: Tue, 8 Jan 2019 22:14:47 -0600

Or rather, move its functionality into nbd-server-add.  And as
a side effect, teach qemu-nbd how to export a persistent bitmap
without having to go through a qemu process and several QMP

Based-on: <address@hidden>
[0/11 bitmaps: remove x- prefix from QMP api]

Patch 5 was very lightly tested; I hope to have more time to play
with that patch alongside Andrey's pending [qemu-img info lists
bitmap directory entries], with an update to iotests to
demonstrate how it is possible to inspect dirty bitmaps by using
qemu-img to learn what is available then qemu-nbd to expose them.
It's still painful that there are no qemu-img commands for
creating a new persistent bitmap; that still has to be done via
QMP on a live guest.

Eric Blake (5):
  nbd: Merge nbd_export_set_name into nbd_export_new
  nbd: Allow bitmap export during QMP nbd-server-add
  nbd: Remove x-nbd-server-add-bitmap
  nbd: Merge nbd_export_bitmap into nbd_export_new
  qemu-nbd: Add --bitmap=NAME option
