LXC containers are isolated from each other. They can't see the processes from other containers.
But the parent, the host, can see all the processes, its own, and those of its containers. This
can be confusing. A small utility, vps, was created. It is a wrapper on top of the
!ps axu
command. For every process, it checks the
!/proc/pid/cgroup
to tell if the process belongs to the host or a container. It inserts a column at the start
of every line. It inserts
!ROOT
for the host process, or the name of the container for container processes.

By default, it prints only the non-interactive process of the host (no tty). It has the following options.
* -x: Prints the processes of the containers
* -i: Prints interactive processes
* -a: Prints all processes
