[Qemu-devel] [question] is it posssible that big-endian l1 table offset referenced by other I/O while updating l1 table offset in qcow2_update_snapshot_refcount?

[Zhang Haoyu]

Hi,
I encounter a problem that after deleting snaptshot, the qcow2 image size is 
very larger than that it should be displayed by ls command, 
but the virtual disk size is okay via qemu-img info.
I suspect that during updating l1 table offset, other I/O job reference the 
big-endian l1 table offset (very large value), so the file is truncated to very 
large.
Any ideas?

Thanks,
