[Lxc-users] [Debian][Squeeze] "Cgroup memory controller: missing", how can I enable this feature ?

[Stéphane Klein]

Hi,

with Debian Squeeze LXC package (stable version, not backported version), when I
execute :

{{{
# lxc-checkconfig
Kernel config /proc/config.gz not found, looking in other places...
Found kernel config file /boot/config-2.6.32-5-amd64
--- 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 namespace: enabled
Cgroup device: enabled
Cgroup sched: enabled
Cgroup cpu account: enabled
Cgroup memory controller: missing
Cgroup cpuset: enabled

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

I've "Cgroup memory controller: missing".

What is the good practice on Debian Squeeze to enable "Cgroup memory controller" ?
I need to recompile manually the kernel to enable this option ?

Best regards,
Stephane
