<p>(1) Here You see the headers of the ps command. Additional you can see the
column VZ-PID. This ist the PID inside the VZ. As You can see in line (7) the
ini process has a VZ-PID:1 but a real PID:3036 outside in the hardware node.</p>
<p>You also see after "COMMAND":<code>[0] load: 0.83 0.57 0.16</code>
[0] is the VZ-Number (here 0=hardware node) and the other numbers are the load.</p>
<p>(2) + (3) This is the vzps.pl script and the ps command</p>
<p>(4) Here you see a <code>vzvtl enter linux1</code> command. The other
two processes (vzctl and bash) are inside the VZ "linux1". See (6)</p>
<p>(5) Here begins the firs VZ "linux1" with the VZ-Number 1 and the
load "0.26 0.20 0.18"</p>
<p>(6) This is the vzctl command started from (4)</p>
<p>(7) this is the bash from the <code>vzctl enter</code> command. Instead of
the ugly <code>/var/lib/vz/root/1/dev/pts/0</code> (whith is much to long) You
see <code>pts/0[V]</code> which fits inside the ps columns.</p>
<p>(8) here You see a ini proces of the VZ linux1. the Real-PID (outside) is
3036, but the PID inside the VZ is 1.</p>
