Hi Andreas, Basically it means that the snapshot was created but the process of the QEMU is still writing on the original volume (The snapshot), so any changes you will made while this VM is running will be in the snapshot.
This could be fixed when restarting the VM (as described in the event), after the restart the QEMU process should run pointing to the right volumes.
