[Qemu-devel] why marking qcow2 img as corrupted

[lampahome]

I tried take snapshots on a demo.qcow2 10 times.
cmd is below:

> qemu-img snapshots -c tag_1 demo.qcow2


when I take snapshots 7 times and console shows:

> mark image as corrupted and preventing from invalid write


and I can't take snapshots anymore then.
Can I avoid this situation or remove the limit?
