lxc bandwidth control using tc
- by kumar
I am trying to restrict bandwidth inside my containers.
I have tried using the following commands , But I think it is not getting effective.
cd /sys/fs/cgroup/net_cls/
echo 0x1001 > A/net_cls.classid # 10:1
echo 0x1002 > B/net_cls.classid # 10:2
tc qdisc add dev eth0 root \
handle 10: htb
tc class add dev eth0 parent 10: \
classid 10:1 htb rate 40mbit
tc class add dev eth0 parent 10: \
classid 10:2 htb rate 30mbit
tc filter add dev eth0 parent 10: \
protocol ip prio 10 \
handle 1: cgroup
Here A and B are containers created with this command.
lxc-execute -n A -f configfile /bin/bash
lxc-execute -n B -f configfile /bin/bash
Whereas configfile contains only this entry:
lxc.utsname = test_lxc
AFter starting the container , I have started vsftpd inside container A and try to access the files using the ftp client from another machine.
Then I killed vsftpd in container A and started vsftpd in container B and try to access the files using ftp client from another machine.
I cannot observe any difference in performance, for that matter it is nowhere nearer to 40mbit/30mbit.
Please correct me whether anything wrong here.
