The bug reported here is not about qcow2 metadata corruption, but about guest data corruption (qemu-img check reports a clean image). It’s entirely possible (and I would even say likely) that there are two different causes.

We know about two guest data corruptions already (which appeared in 4.1), and both seem to only appear on XFS. We have fixed one, the other we don’t quite know yet.

Therefore, I’m wondering whether this is a guest data corruption that we probably already know about (because it’s on XFS), or whether we don’t (because it isn’t).

In any case, I would separate these two bug reports on the basis that this one here is about guest data corruption, whereas 1846427 is about qcow2 metadata corruption.
