These are the steps I followed :
Now we have to install the vserver binary packages. These are the
userland utilities to control virtual servers: 
# wget
http://www.13thfloor.at/vserver/s_rel26/v2.01/util-vserver-0.30.209.tar.gz
# tar -zxvf util-vserver-0.30.209.tar.gz
# cd util-vserver-0.30.209
At this point, make sure you have installed dietlibc and beecrypt/-devel
using the following command:
# yum install -y dietlibc beecrypt-devel
Now build and install the util-vserver tools. Here's an example
(installing tools in /lib and /sbin and also /etc/init.d):
# cd /usr/src/util-vserver-0.30.209
# ./configure --prefix= --sysconfdir=/etc
# make && make install && make install-distribution
Testing
Test if all went well:
# wget http://vserver.13thfloor.at/Stuff/SCRIPT/testme.sh
# chmod 700 testme.sh;./testme.sh
If all went well you get something like this:

The Files

Another utility to control how
vservers function 
/usr/lib/util-vserver 
Main scripts/functions/etc
Setting Up The Virtual Servers
Creating virtual servers is pretty simple from here on. The following
lays it out for you: 
First up you have to create a template from your host system. For that
you have to take a dump of the entire file system minus two
directories, /proc, and /dev:
# mkdir /vservers/template/
# dump 0f - /usr | (cd /vservers/template/ && restore rf -)
Similarly take a dump for the following directories:
/usr /lib /var /etc /opt and /root.
Now you can clean up the template to improve on the speed and size of
the vservers.
create a vserver based on the following command:
# /sbin/vserver <VSERVER_NAME> build -m <BUILD_METHOD>
--hostname <VSERVER_HOSTNAME>
--interface <VSERVER_NAME>=<NET_DEVICE>:<IP>/<CIDR>
Here's a real example:
# /sbin/vserver boing build -m skeleton --hostname boing.lk.com
--interface boing=eth0:192.168.1.10/24
So, our first virtual server will have the following information: 
                       VSERVER_NAME 
boing 
                               FQDN 
boing.lk.com 
                         NET_DEVICE 
eth0 
                                 IP 
192.168.1.10 
                               CIDR 
24 (255.255.255.0) 
                        BUILD_METHOD
skeleton 
Now you have to populate your new vserver with the data from your
template:
# cp -a /vservers/template/. /vservers/boing/
Edit the /etc/hosts and /etc/resolv.conf in the vserver to reflect the
networking settings of your vserver:
# vi /vservers/boing/etc/hosts
# vi /vservers/boing/etc/resolv.conf
Starting The Virtual Servers
We are now doen setting up the vservers. It is now time to keep those
fingers crossed and start our new vserver:
# /sbin/vserver boing start

Well, I was lazy when I tested the IPv6 patch so I hacked up 
http://daniel.hozac.com/vserver/chbind6.c
Compile it with
gcc -lvserver -I<path to kernel tree>/include -o chbind6 chbind6.c
If you're using util-vserver 0.30.210, you should be able to start the 
guest, run
chbind6 -a -n <xid, 42 from your example> -6 <IPv6 address>
and it should be assigned (check /proc/virtnet/<xid>/info to make sure).

Hi there,
somehow it happend that the pointer is very late: linuxwochen Wien
2006 started today with Herbert having an interesting moderation on a
discussion panel relating to "Virtualisation" at all.
He's going to have a speakers task tomorrow 12:00 and having some
other tasks on this event as well , lasting till Friday in Vienna,
location "Urania" - see the link:
  http://www.linuxwochen.at/2006/Wien
Some interviews will be presented on (German) netradio "o94" on
Friday: http://o94.at/programs/netwatcher/

I have found the answer but still have to test it.  Once I do I'll add 
to the Recipes page.
