[Qemu-devel] [PATCH 1/6] qcow2: flush refcount cache correctly in alloc_refcount_block()

update_refcount() affects the refcount cache, it does not write to disk. Therefore bdrv_flush(bs->file) does nothing. We need to flush the refcount cache in order to write out the refcount updates! Signed-off-by: Stefan Hajnoczi --- block/qcow2-refcount.c | 2 +- 1 file changed, 1 insertion(+),

[Qemu-devel] [PATCH 4/6] qcow2: flush in qcow2_update_snapshot_refcount()

[Qemu-devel] [PATCH 5/6] qcow2: drop flush in update_cluster_refcount()
