All the information I have is already in the bug report :) I have no idea what changed in QEMU between 10.0 and 10.1 to cause this, but I have confirmed that the issues mentioned in the original report can be trivially reproduced in trixie, while upgrading *just QEMU* to the version in sid makes it go away. Pinpointing the exact commit that caused this change in behavior is a task better left to someone with experience in QEMU development, and ideally in the storage layer specifically. Once the fix is identified, it should absolutely be backported to trixie (if feasible). -- Andrea Bolognani <[email protected]> Resistance is futile, you will be garbage collected.
