Public bug reported: I set up a br0 (bridge) network on my destop PC in order to allow my virtual machines via KVM to be directly on my LAN instead of natted. Below is my /etc/network/interfaces file The problem is that when logged in to the X session, NetworkManager reports (via D-Bus) that I have no network connection. Any desktop apps that rely on this D-Bus message won't connect. Empathy is a big one that fits in this category. I am forced to assign my eth0 NIC an IP address of 127.0.0.1. This is a bad practice. NetworkManager needs to either understand bridges or have an override of some type. Can I simply remove NetworkManager as a work around? Will the lack of an application producing the network connected D-Bus messge mean that no app will think I am network connected?
