When you start a container, there is a cgroup created automatically 
where all the processes of the container will belong.

In order to modify a cgroup subsystem value use the lxc-cgroup -n name 
subsys_name value

For example : lxc-cgroup -n foo memory.max_usage_in_bytes 268435456

Or specify it in the configuration file to automatically set it up when 
the container starts.

  lxc.cgroup.memory.max_usage_in_bytes = 268435456

Re: [lxc-devel] LXC-Cgroup memory controller

2010-09-07 Thread jorge espada
Thank you Daniel, but in order to do this I must have kernel support ,
right?
dev2:~# lxc-checkconfig | grep memory
Cgroup memory controller: disabled
I think I need this property enabled

Thanks in advance
