Hi, does this patch fixes bug
https://bugzilla.redhat.com/show_bug.cgi?id=1219541 ? Or it unrelated to

Just preserving sparseness is exactly why bdrv_get_block_status_above()
is checked, and this happens always.
detect_zeroes does not preserve sparseness, but detect zeroes in parts
of the source image that are not sparse, and make them sparse in the
target image. This means that it has higher overhead (because all
sectors need to be processed before copying them) and doesn't result in
an exact copy. There may be cases where this is wanted, but in the
common case, it's probably not the right mode of operation.
If you really want to detect zeroes, create the target block driver node
manually (with detect-zeroes=on) and use the blockdev-mirror QMP command
to mirror to it.

yes, you also need to backport the functionality of NBD's write
zeroes( fa778f and 1f4d6d)

I have a sparse qcow2 image(virtual size: 20G disk size: 12G),
# qemu-img info 20G.img
image: 20G.img
file format: qcow2
virtual size: 20G (21474836480 bytes)
disk size: 12G
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
and I tried to qemu-img map --output json xxxx.img, as you can see, the
field of data always is true. when I migrated it with --copy-storage-all,
I get non-spareness image. I tried to read qcow2_co_get_blcok_status,
but I did not find anything issue, if you can give a hint on the case,
i fix it.:-)

To be frank, customers are more concerned about sparseness than overhead.

the target block is created by **bdrv_img_create** and opened by
**bdrv_open** inside qmp_drive_mirror, it also mean than we only enable
detect-zeroes while
its opened, i don't find qmp cmd to only enable it, if I understand
correctly.

Did you use metadata preallocation? If so, you explicitly requested all
clusters to be allocated.

All generalisations are wrong.
We could be talking about the majority of users (the QEMU project
doesn't have customers), but even then I doubt you're right, especially
when using preallocation which is a tool for giving up sparseness in
favour of improved performance of the first write to a cluster.

That's why I said you use blockdev-mirror instead drive-mirror.

Yes, I created the image with metadata preallocation. I see. its why
qcow2_get_cluster_type always return QCOW2_CLUSTER_NORMAL.

The majority of users.:-) forgive my word.

This patch is able to handle this case. In fact I only hope to use
preallocation to improve performance rather than become a sparseness
image while live migrating.
it would waste a large mount of disk space, as most of our VM's data
disk(/dev/vdb) is larger than 1TB. As you said, We can use
blockdev-mirror and manually enable detect-zeros
on new qemu verison(>2.6), but for less than 2.6, we also need to do it
in drive-mirror.

Got it, unfortunately my qemu version does not contain this command.
in order to use it, I also need to modify my libvirt. its not
temporarily available to do this. I would consider the my next release
to do it.:-)

Got it, I would also backport it to my qemu repo. thank you Eric.;-)
