KEMP Virtual LoadMaster

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. The following instructions describe how to install a Virtual LoadMaster on a VMware ESXi environment.

The VLM is packaged with an .ovf for ease of deployment. This file can be freely downloaded from https://freeloadbalancer.com/download/ . Unzip the contents of the file to an accessible location. Time to deploy the OVF file.

Disk Format – Thin/Thick provisioned format

Once setup is done, power on the virtual machine and select console tab.

Time to configure virtual server. I have already added virtual servers.

Virtual Servers

Click Modify, if you have already added Virtual IP. If not, click add new.

Modify Kemp VS

Here 172.XX.XX.139:8080 is my virtual IP. This IP will be my entry point from the client. That means, on client side, this IP will be used and in the following configuration, we will add two real IPs. Basically, these IPs are from 2 different computers. The concept is, if one Server (IP) is down, Load-Balancer will connect to second server (IP). Client will not notice this change. Similarly, based on Scheduling Method ( see above ), Load-Balancer will decide which way to go.

Real Servers

This is the simple Load-Balacer configuration. For more details, see official documentation from KEMP.
