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,
Zhang Haoyu
