VLM for Xen (Para Virtualized)
Installation Guide
1 Introduction
The KEMP Virtual LoadMaster is a version of the KEMP LoadMaster that runs as a virtual
machine within a hypervisor and can provide all the features and functions of a hardware-based
LoadMaster.
This document describes the installation of the Virtual LoadMaster (VLM) within a Xen, para-
virtualized environment.
The VLM has been tested with Xen.org versions 3.1, 4.0 and 4.1.
There are several different versions of the VLM available. Full details of the currently supported
versions are available on our website:
The Xen virtual machine guest environment for the VLM, at minimum, must include:
1 GB RAM
32 GB virtual hard disk capacity
Para-virtualization requires some modification of the guest OS or application. The guest OS or
applications are aware that they are in a virtual environment which allows for a near-native
performance.
There may be maximum configuration limits imposed by Xen such as maximum RAM per VM,
Virtual NICs per VM etc. For further details regarding the configuration limits imposed by Xen,
please refer to the relevant Xen documentation.
A wide variety of Linux distributions can be used as the Dom0 operating system. For a full list of
the compatible Linux distributions, please refer to
KEMP LoadMaster has been tested with OpenSUSE 12.1 as the Dom0 operating systems and the
3.1 Xen.org version.
If you have any issues with the Virtual LoadMaster when using a different combination of
Xen.org versions and Linux distributions as the Dom0, then please contact KEMP Support.
