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 an Oracle VirtualBox hypervisor environment.
The VLM has been tested with Oracle VirtualBox 5.1.38.
The Oracle VirtualBox environment for the VLM, at minimum, must include:
2 x virtual processors
2 GB RAM
16 GB disk space (sparse recommended - this may grow, depending on usage)
There may be maximum configuration limits imposed by Oracle such as number of virtual CPUs, maximum RAM per VM or Virtual NICs per VM etc. For further details regarding the configuration limits imposed by Oracle, please refer to the relevant Oracle documentation.
The following instructions describe how to install a Virtual LoadMaster on an Oracle VirtualBox.

The LoadMaster is now fully installed and ready to be used. For further information on how to configure and implement the Virtual LoadMaster, please refer to the LoadMaster documentation which can be found here: https://kemptechnologies.com/documentation.
In case you move a VLM system to a different virtual machine, ensure that the MAC addresses of the virtual machine's NICs stay the same. It is recommended to configure static MAC addresses for all NICs within virtual machines.
For further information on configuring static MAC addresses, please refer to the relevant Oracle documentation.
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.
When you add a new NIC to the VLM and reboot the machine, addresses are assigned to the NICs based on the order they are detected during the device scan. There is no guarantee that the NICs will retain the addresses they had previous to the reboot.
Thus, if you had a VLM setup with NIC0 assigned to eth0 add NIC1 assigned to eth1, after adding a third NIC, NIC3, and rebooting, there is no guarantee that that NIC0 and NIC1 will remain assigned to the interfaces they were assigned to previous to addition of an extra NIC. For example NIC0 could end up assigned to eth1 and NIC 1 assigned to eth2.
This will not occur if no additional NICs are added. For further information on ensuring that the ordering remains constant, please refer to the Oracle VirtualBox documentation.
