I seem to recall some churn about how to handle devices when a netns is destroyed. At one point they were moved back to the initial netns. If the behavior you're seeing with 2.6.35-25-virtual is still happening with 2.6.39, then lxc will need to work around that by moving the nic back to the host netns before shutting down the container (or kernel behavior fixed/changed). thanks, -serge -- Forrester Wave Report - Recovery time is now measured in hours and minutes not days.
