Hi Christian,

I'm a Louis' coworker and I also worked on this issue. 
We first did some tests starting from 2.12 to find a workaround with qemu-img. 
It seemed that this version of qemu was immune to our bug. Then, we backport 
packages from cosmic and reproduce our production issue.
I'm not familiar enough to qemu code and I was unbale to find the commit which 
fix the issue.
Thanks
