[Libvir] A sample program to create a Linux Container

Attached is a simple program that uses the clone() function to create a
container. This is not intended as a patch - just an example of what
creating a Linux Container looks like. Something along these lines will
be used by the Linux Container driver to start the domain. The code run
within this container is really simple. It just mounts the /proc file
system and then dumps the ps output to a file showing that the container
is in separate process space.
To run this you will need to have PID namespaces support enabled. Turn
on CONFIG_PID_NS when compiling the kernel. You must run the program as
root or the clone() call will fail.
Any questions or comments are welcome. Thanks!
