I'm not quite sure what you want to do, but each CT has it's own
virtual /proc. If you check for example the traffic of the
veth/venet interface inside a CT you'll see only the information for
the particular CT. Or you want to have a module showing information
for all CTs?<br>

Thanks very much vagin£¬I have access to CT0, I want to have a
module to monitor different VM's traffic, and each VM can see its
own traffic insdie, is it possible?

*Hi, all:*<br>
*I'm wondering if I can write and execute virtual file
system like /proc in OpenVz VMs. For example , write a
module to check the incoming traffic rate of this VM and
show it in this VM's /proc as a file. I know different VMs
share one kernel, is it possible??? Thanks very much
guys.*<br>

Yes. It's possible. You can write file system as module,
load it from host (CT0) and mount your file system from CT.<br>
And you can't do that, if you have access to CT only.
