These are the steps I followed :
Now we have to install the vserver binary packages. These are the
userland utilities to control virtual servers:
# 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
Test if all went well:
# chmod 700 testme.sh;./testme.sh
If all went well you get something like this:

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 --------------------------------------- end if file ----------------- > > > secure-mount: chdir("/tmp"): No such file or directory > > looks like some /tmp either on the guest or on > the host is missing, or maybe some permissions > are not set properly ... > > > /etc/vservers/boing/fstab:2:1: failed to mount fstab-entry > > this is likely the result of /tmp not being > there so mounting the tmpfs fails > > > find: var/run: No such file or directory > > similar for var/run as it seems > > > fakerunlevel: open("/var/run/utmp"): No such file or directory > > > > > > Failed to start vserver 'boing' > > > > howto fix this errors? > > first, let's figure the tool version and how > you installed the guest ... > > best, > Herbert > > > Thanks > > > > Varun > > _______________________________________________ > > Vserver mailing list > > Vserver@list.linux-vserver.org > > http://list.linux-vserver.org/mailman/listinfo/vserver > _______________________________________________ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserverReceived on Wed May 31 14:32:27 2006
