[Users] Docs to understand how OpenVZ is implemented.

[Kentaro Ebisawa]

Hi,

Are there any documents/blogs/books I should read to understand how OpenVZ is implemented?
I went over http://wiki.openvz.org/Main_Page , searched Google but could not find details.

I'm especially interested in networking code.
For example ...
 * What was added to networking code?
   vzethdev.c and what?
 * code path difference compared to vanilla kernel when receiving/sending packet.
 * How cgroup is used.

I'm trying to read the source code but wanted to know overall design for better and faster understanding.
Please let me know if this is better question for devel at openvz.org.

Thanks!
