Changes by last author:

Added:
== Test configuration ==

Host:

* Debian Etch AMD64

* Kernel: 2.6.15.4-vs2.0.2-rc9

* util-vserver 0.30.210 + patche (see below)

Guest:

* SLES 9

== Running SuSE vservers on a Debian server ==

=== Installation ===

Debian is lacking the required rpm tools to install a SuSE/SLES? system directly (the required apt-rpm is available in source only for apt-0.5.xx, and Debian is already at 0.6.xx).

* install SuSE on raw metal

* boot from CD (SuSE or Debian whatever you prefer)

* tar the whole system, copy it to the vserver host and untar it to desired vserver location, usually /var/lib/vservers/<servername>

* create /etc/vservser/<servername> manual (or copy from other vserver)

=== post install cleanup ===

* remove some startup service, either delete the /etc/init.d/.... links or run the following from inside the vserver:

<code>

chkconfig -d -f boot.swap boot.isapnp boot.idedma boot.loadmodules > boot.device-mapper boot.md boot.proc boot.shm boot.sched > boot.rootfsck hotplug boot.localfs boot.crypto boot.clock > boot.scpm boot.ipconfig

chkconfig -d -f coldplug irq_balancer random network fbset powersaved kbd hwscan

</code>

* remove unneeded packages:

<code>

rpm -e irqbalance kernel-smp grub reiserfs xfsprogs raidtools ntfsprogs > module-init-tools mkinitrd powersave hotplug mdadm

</code>

Note: there are a number of redundant packages remaining that can not be removed due to yast2 depending on them.

=== initscripts ===

SuSE's /etc/init.d/rc expects two enviromnet variables: RUNLEVEL and PREVLEVEL. the vserver.start scripts failes to set those. We've got workarrounds:

a) edit /etc/init.d/rc to set those values (not recomended)

b) apply the following patch to vserver.start to set the values:

<code>

--- vserver.start.orig 2006-03-02 10:37:49.000000000 +0000

+++ vserver.start 2006-03-02 10:10:36.000000000 +0000

edit me: do we need to modify the vserver.stop script as well?
