KB2010010402: Install guide for xn-mem without additional modules

This guide shows how to use xn-mem of the xn-suite without using the other components.

Install the xn-suite as described in the install guide .

Disable all modules in "/etc/xncore/modules.conf" except xn-mem. Open the config file with an editor and change it to the following:
XNMANAGE=no
XNMEM=yes
XNMON=no
XNTRAFF=no
XNWEB=no


Restart the services with disabled services not beeing started:
/etc/init.d/xn-daemon restart

Create a config file for each vserver: "/etc/xncore/vserver/vservername.conf". Ensure that the value for vservername is the name of the Xen DomU.

Insert the minimum and maximum memory values into the vserver config file as follows (values in MByte):
memory_min=256
memory_max=1024


When making changes to that vserver config files the daemon does not have to be restarted.

Important: If you are using vservers running Linux kernel 2.6.18 or older please pay attention to the following KB article:
