Addon:

This was with kernel 2.6.35-25-virtual

With kernel 2.6.32-30-server I even cannot start the container:

root at zoo:~# lxc-start -f /lxc/ubuntu.cfg -n ubuntu
lxc-start: failed to move 'eth1' to the container
lxc-start: failed to create the configured network
lxc-start: failed to spawn '/sbin/init'

though eth1 is there:

root at zoo:~# ethtool eth1
