Hey there!
I'm experiencing a strange behavior with libvirt and backing chains.
Getting higher than the first overlay results in a permission denied to the base image and
I can't start any machine.
# Results while attempting to start machine
(after every attemt the whole files from ./houseBackup are restored)
Base.img (ok - Win 10 Installation starting)
FirstFloor.ovl (ok - Win 10 Installation starting)
SecondFloor.ovl (permission denied -> Base.img) => assumed Bug
Roof.ovl (permission denied -> Base.img) => assumed Bug
The bug is described in detail here together with a minimal example.
But maybe I'm still doing something wrong and somebody can give me a heads up =).
