Hi, I'm not at all an dconf expert. But after identifying that even base dconf-editor does not let you save things I think we can eliminate virt-manager from the equation.
I have added a task to this bug for d-conf to get maintainers of that package to take a look. They might know where to look and after what. ** Also affects: d-conf (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of DX Packages, which is subscribed to d-conf in Ubuntu.
