[Lxc-users] How make top, meminfo etc. to show the limits of the container?

[atp]

Hi,

Its not as simple as it seems. What you're asking for is to selectively
hide or modify what gets shown to container processes by the /proc file
system. In other words making /proc container aware. /proc is already
partially there - with the pid namespace, but not for ram and cpus. 

We've tried a couple of approaches - FUSE based overlay file system etc
- and at the last lxc dev call the way forward was proposed as being an
in kernel file system integrated with the cgroups subsystem, bind
mounted to the containers /proc.

At the moment, the containers I'm running adopt a far more hacky
solution to this by patching the /proc filesystem itself. 

Patch for cpu limiting proc stat is at;
