How to install OpenQRM 4.8 with LXC containers in Debian Squeeze/Ubuntu 10.04 LTS: Step by Step (Page 3)

C) INSTALL LXC

C1)

Quote:

#aptitude install lxc

C2)

Quote:

#mkdir /cgroup

C3) Add the following line in /etc/fstab using a text editor:

Quote:

cgroup /cgroup cgroup defaults 0 0

C4)

Quote:

#mount -a

C2)

Quote:

#lxc-checkconfig

You will see something like below:

Quote:

$ lxc-checkconfig
Kernel config /proc/config.gz not found, looking in other places...
Found kernel config file /boot/config-2.6.32-5-686
--- Namespaces ---

Network namespace: enabled
Multiple /dev/pts instances: enabled

--- Control groups ---

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

Note : Before booting a new kernel, you can check its configuration
usage : CONFIG=/path/to/config /usr/bin/lxc-checkconfig

The only thing that you cannot do with the vanilla debian squeeze kernel reporting 'Cgroup memory controller: missing' parameter is to allocate memory. One can recompile the kernel with memory controller enabled in a debian way (shall explain in another tutorial if needed), but it hogs 2-3% of CPU resources.
