The Progress Kemp Virtual LoadMaster is a version of the 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 VMware hypervisor environment.
The Virtual LoadMaster is VMware ready.
The Virtual LoadMaster is supported and has been tested with:
VMware ESXi 5.5 through ESXi 7.0 Update 3c (7.0.3)
vCenter Server 5.5 through vCenter Server 7.0 Update 3c (7.0.3)
There are several different versions of the VLM available. Full details of the currently supported versions are available on our website: www.kemptechnologies.com.
The VMware virtual machine guest environment for the VLM, at minimum, must include:
- 2 x virtual CPUs (reserve 2 GHz)
- 2 GB RAM
- 16 GB disk space (sparse where possible)
There may be maximum configuration limits imposed by VMware such as maximum RAM per VM, Virtual NICs per VM and so on. For further details regarding the configuration limits imposed by VMware, please refer to the relevant VMware documentation.
2 Best Practices
Some best practices to be aware of before deploying a LoadMaster on VMware are below:
- Configure an existing or new load balancing port group for the relevant VLAN to avoid port flooding
- Use the VMXNET3 network adapter type when deploying the VLM
Reordering happens only when using 4 or more VMNET3 network adapters. This issue does not occur if using e1000 network adapters. Refer to the following Knowledge Base article for further information: When adding 4 or more VMXNET3 NICs to a VLM in VMware, the order is incorrect.
- When using High Availability (HA), ensure that MAC Address Changes and Forged Transmits are both selected and set to Accept. Ensure this is forced (hard coded) on the port group as any changes to the vSwitch will affect all port groups by default.
- When using HA and the LoadMasters are on different hosts: To prevent the transmission of RARP packets from being sent every time a Virtual Machine is powered on, set the Notify Switches option to No.
3 Installing Virtual LoadMaster (VLM) using vSphere
The following instructions describe how to install a Virtual LoadMaster on a VMware ESXi environment using the VMware vSphere client.
3.1 Static MAC Addresses Must Be Configured
If you move a VLM system to a different Virtual Machine, ensure that the MAC addresses of the Virtual Machine’s NICs stay the same. Static MAC addresses must be configured for all NICs within Virtual Machines.
For further information on configuring static MAC addresses, please refer to the relevant VMware documentation.
A static MAC address is needed due to the Progress Kemp license being tied to the MAC address. If the MAC address changes, the license can break and you must contact Progress Kemp Support to restore your license.
3.2 Download the OVF File
The VLM is packaged with an .ovf file for ease of deployment. This file can be freely downloaded from Kemp for a 30 day evaluation period. To download the VLM please follow the following instructions.

5 Upgrading Your Virtual Machine
The VMware VLM is delivered as a hardware version 10 virtual machine. You can upgrade to a higher virtual machine number as needed. Before upgrading, first take a backup or snapshot of the virtual machine. If you do this, you can reverse the upgrade if needed.
For further details on upgrading a virtual machine, refer to the VMware documentation.
If you have the VMware Tools package installed on LoadMaster, you must upgrade to the appropriate version of VMware Tools for the target hardware version before you upgrade the virtual hardware. Ensure that the version of VMware Tools is appropriate for the target hardware version.
6.1 Factory Reset
If you perform a factory reset on your VLM, all configuration data, including the VLM’s IP address is deleted. During the subsequent reboot the VLM attempts to obtain an IP address using DHCP. If the VLM is on a different subnet to the DHCP server then an IP address will not be obtained and the IP address is set to the default 192.168.1.101.
The VLM may not be accessible using this address. If this is the case then you must run through the quick setup using the console as described in the Configuring the LoadMaster Using the Console section.
6.2 VMware Tools
The VLM supports integration with VMware Tools. For more information, please refer to the VMware Tools Add-On Package, Feature Description.
6.3 Working with VMware Virtual Switches
When working with VMware Virtual Switches within your configuration, please ensure that the value of the Forged Transmit Blocking option is Accept. If this option’s value is Reject, the LoadMaster is prevented from sending traffic as it appears to come from nodes on the network other than the LoadMaster.
Please refer to your VMware documentation for further details on how to configure the VMware Virtual Switch.
