I want to set up a mesh network using batman-adv, but NetworkManager keeps taking control of the second adapter... I need to be able to selectively tell NetworkManager not to manage one specific device.

Is this possible?

NetworkManager doesn't take control of interfaces listed in /etc/network/interfaces, so put the following line in that file:

iface wlan0 inet manual

This will make NetworkManager ignore wlan0.

In Ubuntu 14.10 and before, NetworkManager correctly ignored interfaces created by VirtualBox (vboxnet*). In 15.04 it insists on managing them and this solution does not work. See bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1485558 . In the meantime, any solution working on 15.04 would be nice! – Stéphane Gourichon Aug 19 '15 at 16:47
