Subject: [Qemu-devel] [PATCH 0/2] bitmaps: merge bitmaps from different nodes
Date: Thu, 16 May 2019 15:27:23 +0300 [thread overview]
Message-ID: <20190516122725.132334-1-vsementsov@virtuozzo.com> (raw)
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.
Vladimir Sementsov-Ogievskiy (2):
qapi: support external bitmaps in block-dirty-bitmap-merge
iotests: test external snapshot with bitmap copying
