I tried to configure QOS (with bandwidth, classes, and services) but it's not working at all.
Restarting QoS with restartqos.py the output is this:

A bug? Any suggestion?
 ???

Problem is with TAP interface (OpenVPN lan2lan)  >:(
There is no ifb device linked to tap1 so restartqos fails.
I need to set qos for vpn tunnel (VoIP traffic): is there another way to ensure priority for VoIP packets?

Solved!

Default number of ifb devices is 2, and I had 3 qos devices (green, red, vpn).
If you have more than 2 QoS devices you have to modify /etc/modprobe.conf and add a line:

options ifb numifbs=X (where X is the number of qos devices you need)
