Comment 4 for bug 1724441

Hey, thanks for the pointers, I've been looking into this a bit and performed the following:

- Set `bridge_helper` correctly in `/etc/libvirt/qemu.conf` - it was commented out and pointing to the wrong binary
- Made qemu-bridge-helper set-uid
- Created an appropriate /etc/qemu/bridge.conf
- Restarted all the services

I'm getting a different error message now, at least.

As far as I can tell, gnome-boxes is just a libvirt client, so it just expects a working installation.
