Installing Ubuntu 8.04 (Hardy) as a Vserver guest

As Ubuntu 8.04 (Hardy) is the latest LTS release of Ubuntu, it would be a good choice to install as a server. A lot of this information is from the OpenVZ guide at https://help.ubuntu.com/community/OpenVZ.

This guide requires that you have configured your /etc/vservers/.default correctly

[edit] Prerequisites

• debootstrap

 [Vserver-host] $ sudo apt-get install debootstrap

[edit] Debootstraping in Ubuntu

 [Vserver-host] $ vserver hardy-guest build -m debootstrap \
 --context 42 --hostname hardy-guest --force \
 --interface eth0:10.0.0.123/8 \
 -- -d hardy -m http://us.archive.ubuntu.com/ubuntu/ \
 -- --arch=i386 --exclude=udev

You will receive the following warning 5 times (obviously):

 W: Failure while configuring base packages.  This will be attempted 5 times.

You can safely ignore them, as we will fix this later

[edit] Removing unneeded services

By default klogd and rmnologin runs at startup of the guest, it is not necessary, and will slow down the startup time of your guest, you better remove them

 [Vserver-host] $ cd /[path_of_vservers]/hardy-guest/etc/rc3.d
 [Vserver-host] $ rm S11klogd S99rmnologin

You should also remove unneeded shutdown scripts

 [Vserver-host] $ cd /[path_of_vservers]/hardy-guest/etc/rc6.d
 [Vserver-host] $ rm *

You should add a link for killing sysklogd

 [Vserver-host] $ ln -s ../init.d/sysklogd K11sysklogd

[edit] Starting guest and fixing group 11 issue

Now it is time to start your new vserver and enter it:

 [Vserver-host] $ vserver hardy-guest start

It will return the following:

 /etc/init.d/rc: 166: cannot open /dev/console: No such file
 * Starting system log daemon...
  ...done.
 * Running local boot scripts (/etc/rc.local)
  ...done.

Then you can enter your vserver

 [Vserver-host] $ vserver hardy-guest enter

It will return the following:

 id: cannot find name for group ID 11

[edit] Fixing the "/etc/init.d/rc: 166: cannot open /dev/console: No such file" issue

Open /etc/init.d/rc in your favorite editor

 root@hardy-guest:/# vim /etc/init.d/rc

Find the following lines and comment them out by perpending them with an "#" (this has been done in the example) They will be at line 163-166

 # Set onlcr to avoid staircase effect.
 #if [ "$QUIET" != yes ]; then
 #    stty onlcr </dev/console >/dev/console 2>&1
 #fi

Save and quit

[edit] Fixing the "id: cannot find name for group ID 11" issue

I don't know what the group really shoud be, but I just added the group "void" as group 11. Someone who knows what it should be, could probably correct it.

 root@hardy-guest:/# groupadd -g 11 void

[edit] Removing unneeded packages

There are some packages you obviously would not need in a vserver-guest:

• DHCP3
• busybox-initramfs
• console-setup
• dmidecode eject
• ethtool
• initramfs-tools
• klibc-utils
• laptop-detect
• libiw29
• libklibc
• libvolume-id0
• mii-diag
• module-init-tools
• ntpdate
• pciutils
• pcmciautils
• ubuntu-minimal
• udev usbutils
• wireless-tools
• wpasupplicant
• xkb-data
• tasksel
• tasksel-data

So you should start up your new guest and enter it and remove them.

 [hardy-guest] $ apt-get remove --purge busybox-initramfs console-setup dmidecode eject \
 ethtool initramfs-tools klibc-utils laptop-detect libiw29 libklibc \
 libvolume-id0 mii-diag module-init-tools ntpdate pciutils pcmciautils ubuntu-minimal \
 udev usbutils wireless-tools wpasupplicant xkb-data tasksel tasksel-data \
 dhcp3-client dhcp3-server

[edit] Finished

Now you have installed hardy from debootstrap, and hopefully everything is working

Remember that you will have to create symlinks to services in /etc/rc6.d in order for them to be stopped when running 'vserver [vservername] stop'
