From c3cf3c43a0bb2e0e4909c32821e20f607635ec85 Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Fri, 24 Apr 2015 15:52:56 +0200 Subject: [PATCH] lxc: don't up the veth interfaces unless explicitly asked to Upping an interface for no reason and not configuring it is a cardinal sin. With the default addrgenmode if eui64 it sticks a link-local address to the interface. That is not good, as NetworkManager would see an address configured, assume the interface is already configured and won't touch it iself and the interface might stay unconfigured until the end of the days.
