Hi all! It's a continuation for "bitmap migration bug with -drive while block mirror runs" <315cff78-dcdb-a3ce-2742-da3cc9f0c...@redhat.com> https://lists.gnu.org/archive/html/qemu-devel/2019-09/msg07241.html
The problem is that bitmaps migrated to node with same node-name or blk-parent name. And currently only the latter actually work in libvirt. And with mirror-top filter it doesn't work, because bdrv_get_device_or_node_name don't go through filters. Fix this by handling filtered children of block backends in separate. v2: rebase on current master Max Reitz (1): block: Mark commit and mirror as filter drivers Vladimir Sementsov-Ogievskiy (4): migretion/block-dirty-bitmap: refactor init_dirty_bitmap_migration block/dirty-bitmap: add bdrv_has_named_bitmaps helper migration/block-dirty-bitmap: fix bitmaps migration during mirror job iotests: 194: test also migration of dirty bitmap include/block/block_int.h | 8 ++- include/block/dirty-bitmap.h | 1 + block/commit.c | 2 + block/dirty-bitmap.c | 13 ++++ block/mirror.c | 2 + migration/block-dirty-bitmap.c | 114 +++++++++++++++++++++++---------- tests/qemu-iotests/194 | 14 ++-- tests/qemu-iotests/194.out | 6 ++ 8 files changed, 119 insertions(+), 41 deletions(-) -- 2.21.0
