(Get the code!)
Quickly documenting another potentially exploitable use case before I call it a night. It might be possible to hit this when calling shelve and then unshelve against an instance. I've not had time today to confirm but I suspect writing qcow2 headers to the root disk that we snapshot as part of the shelving process would also cause the imagebackend to incorrectly identify the disk once the we unshelve the instance. I'll look into this tomorrow morning.
