[Qemu-devel] [PATCH v2 0/2] bitmaps: merge bitmaps from different nodes

Posted by Vladimir Sementsov-Ogievskiy 4 years, 11 months ago

Hi all!

We need to copy bitmaps to new top node on external snapshot, to
not break incremental backup chain.

The only thing to do is to allow block-dirty-bitmap-merge to work
with different nodes, here it is.

v2: use 'alternate' type in qapi for specifying source bitmap
    instead of adding new field external-bitmaps [Eric]

Vladimir Sementsov-Ogievskiy (2):
  qapi: support external bitmaps in block-dirty-bitmap-merge
  iotests: test external snapshot with bitmap copying
