it is problematic that traceback created from Virt manager is not enough
to debug virt manager.
but here it goes:
No guest, no guest network, i did not said there is a ui option called
"on virtual network creation" just go to "virtual networks" on ui and
push play button to start network. it throws up the posted Traceback on
UI.
Package: virt-manager
Version: 1:1.3.2-3ubuntu1.16.04.4
Priority: optional
Section: universe/admin
Origin: Ubuntu
Maintainer: Ubuntu Developers <ubuntu-devel-disc...@lists.ubuntu.com>
Original-Maintainer: Debian Libvirt Maintainers
<pkg-libvirt-maintain...@lists.alioth.debian.org>
there is no info that i can give you to solve this bug. because problem
lies within code that is ugly filled with unreasonable assumptions. They
should not code on assumptions they did not checked first.
here is the default one:
Error starting network 'default': internal error: Child process

it is a fresh install. i suspect if i run virt-manager with sudo it will go
away but i won't.
