[lxc-devel] How to know that whether a process run inside a container or not?

[liu.sp at neusoft.com]

Hi Greg Kurz ,Daniel Lezcano,

   Could you give me some guidance on how to check if a process run 
inside a container 
or host?

   In the kernel space ,we can check the level of pid to do it.
   But in the user space ,how to check it ?
   

Best regards
Spring
