This keeps happening for me every time, and I just ignore the .pacnew file. It should actually not be considered on updates because the settings stored therein can be modified through the virt-manager UI anyway. I used to think that adding the path to backups=() in the PKGBUILD would solve the problem, thinking further about it, removing it from the package files completely might be a better idea, though. One other alternative I can think of would be to name your default network differently as to not clash with the package provided setting. cheers! mar77i
