This makes complete sense, I just can't figure out how qemu treats this because when I tried it on upstream now, it ended up with a segfault :)
A qemu segfault? Can you post the reproduction recipe?
I tried my first thing and it crashed. This is enough: qemu-img create -f qcow2 -o backing_file=gluster://test1.qcow2,backing_fmt=qcow2 test.qcow2 1M qemu-img convert -f qcow2 -O raw test.qcow2 output.img I just haven't had the time to check why and where it segfaults... Martin
