Hi All,

It seems we are missing some kernel options regarding cgroups and veth which are needed to run lxc.

CONFIG=/home/build/OrangePI-Kernel/linux-3.4/.config lxc-checkconfig

--- Namespaces ---
Namespaces: enabled
Utsname namespace: enabled
Ipc namespace: enabled
Pid namespace: enabled
User namespace: enabled
Network namespace: enabled
Multiple /dev/pts instances: enabled

--- Control groups ---
Cgroup: enabled
Cgroup clone_children flag: enabled
Cgroup device: enabled
Cgroup sched: enabled
Cgroup cpu account: enabled
Cgroup memory controller: missing
Cgroup cpuset: missing

--- Misc ---
Veth pair device: missing
Macvlan: missing
Vlan: missing
File capabilities: enabled


I managed to build the veth out of tree, but I do not seem to be able to cross compile the kernel from Loboris'  github on my Debian 7  desktop.

Maybe these can be included in the next kernel Loboris releases as running lxc containers is quite a nice thing to be able to do.

Thanks.

I second this! Containers would open a whole new lot of experiences with those little boards.

I've updated the kernel you can try it.

Download update_kernel.sh script:
  1. wget http://loboris.eu/update_kernel.sh
  2. sudo mv update_kernel.sh /usr/local/bin
  3. sudo chmod +x /usr/local/bin/update_kernel.sh
Copy the Code
To update the kernel to the new (test) version run:
  1. sudo update_kernel.sh test
Copy the Code
boris@UbuntuMate:/home/LoBo2_Razno/OrangePI/kernel_3.4.9/linux-3.4$ CONFIG=./.config lxc-checkconfig

Hi Loboris,

  1. root@lxc-host:~# lxc-ls --fancy
  2. NAME           STATE    IPV4           IPV6  AUTOSTART  
  3. ------------------------------------------------------
  4. webmon-jessie  RUNNING  192.168.99.21  -     YES        
Copy the Code


This works great , now I can move some of my Banana Pi containers over to the Orange Pi Pc.

The test container already feels much more responsive .

Thank you Loboris.

Hi Kpox,

I just did a test lxc creates a ubuntu container just fine on debian.

Are you sure you did a modprobe as  provided in the post of Loboris.

Below a short excerpt of how I installed the Ubuntu container.
# uname -a
Linux lxc-host 3.4.39-02-lobo #1 SMP PREEMPT Tue Nov 10 10:37:50 CET 2015 armv7l GNU/Linux

# lsb_release -a
No LSB modules are available.
Distributor ID:        Debian
Description:        Debian GNU/Linux 8.2 (jessie)
Release:        8.2
Codename:        jessie

# dpkg -s lxc|grep Version

# apt-get install -y ubuntu-archive-keyring

# lxc-create --name ubuntu -t ubuntu
Checking cache download in /var/cache/lxc/precise/rootfs-armhf ...
Installing packages in template: ssh,vim,language-pack-en
Downloading ubuntu precise minimal ...
--- A lot bla bla bla

When finished just start it
# lxc-start -n ubuntu

# lxc-ls --fancy|grep ubuntu
ubuntu         RUNNING  192.168.99.23  -     YES

Hi Drakoh,

The Orange Pi provided kernel is just too old for docker, as at minumun a 3.10 kernel is required, we will need to wait (a long time) until the h3 support is mainlined.

Or buy one of the boards which do already have a more modern kernel support.

Such as the boards already supported by Debian natively.

https://wiki.debian.org/InstallingDebianOn/Allwinner

or

https://wiki.debian.org/ArmHardFloatPort/CuBox-i

As I have both boards I know these are well supported.

Hi retroman!

I've read the warning in the log, but I hoped there is a way to make it work.
Guess I have to learn the usage of LXC.
