[libvirt] [PATCH v2 0/9] qemu: Blockdevize external snapshot creation (blokcdev-add saga)

[Peter Krempa]

Patches 1-5 of the original series were already pushed.

Patches 1-3 of this series are new and deal with fixing of a image
locking bug which was added during the blockdev-add saga as we've
changed the handling of the 'readonly' flag of an image.

Patch 4 is new and should solve review feedback which complained about
function naming.

The rest of the series is almost exactly as in previous posting with
following exceptions:

1) Review feedback incorporated and R-b's applied.
2) Patch 6/9 has a different summary
3) Patch 8/9 fixes a memory leak/crash as a part of the cleanup was
   misplaced out of the cleaning loop (while still using the 'i' to
   dereference arrays).
4) Conflicts with 4/9 resolved.

Peter Krempa (9):
  qemu: snapshot: Fix image lock handling when taking a snapshot
  qemu: snapshot: Save status and config XMLs only on success
  qemu: snapshot: Move error preservation to

    code or qemu
