I changed 'lxcbr0' by veth pair name(appear when start container after
use ifconfig cmd, I can't set veth pair name, lxc.network.veth.pair no
effect), and use:<br>$sudo tc qdisc add dev vethxxxxx root handle 1: htb default 2<br>
$sudo tc class add dev vethxxxxx parent 1: classid 1:1 htb rate 10mbit<br>$sudo tc class add dev vethxxxxx parent 1: classid 1:2 htb rate 1mbit<br>$sudo tc filter add dev vethxxxxx protocol ip parent 1: prio 1 handle 1: cgroup<br>
and test again, It's work. So I think it's a problem with net_cls, or lxc.cgroup.net_cls.classid no effect.<br>I feel confused.<br><br>I found many tutorials, but they maybe used for privileged container. </p>
