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.
There are several different versions of the VLM available. Full details of the currently supported versions are available on our website: http://www.kemptechnologies.com.
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.
2 Installing Virtual LoadMaster (VLM) using Oracle VirtualBox
The following instructions describe how to install a Virtual LoadMaster on an Oracle VirtualBox.

11. Click OK .
12. You should now connect to the Home screen of the LoadMaster.
13. Go to System Configuration > Network Setup in the main menu.
14. Click the eth0 menu option within the Interfaces section.
15. In the Network Interface 0 screen, enter the IP address of the eth0 interface, the network facing interface of the LoadMaster, in the Interface Address input field.
16. Click the Set Address button.
17. Click the eth1 menu option within the Interfaces section.
18. In the Network Interface 1 screen, enter the IP address of the eth1 interface, the farm-side interface of the LoadMaster, in the Interface Address input field.
19. Click on the Set Address button.
This interface is optional, depending on the network configuration.
20. Click on the Local DNS Configuration > Hostname Configuration menu option.
21. In the Hostname configuration screen, enter the hostname into the Current Hostname input field.
22. Click the Set Hostname button.
23. Click the Local DNS Configuration > DNS Configuration menu option.
24. In the DNS configuration screen, enter the IP address(es) of the DNS Server(s) which is used to resolve names locally on the LoadMaster into the DNS NameServer input field.

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 downloaded from the http://kemptechnologies.com/documentation page.
3.1 Configuring the LoadMaster Using the Console
If the LoadMaster does not automatically obtain an IP address using DHCP, or if the user prefers to configure the LoadMaster using the console, then the following configuration steps must be completed before starting the LoadMaster.
1. Login into the LoadMaster using the console with the following settings:
- lb100 login: bal
- Password: 1fourall
2. Enter the IP address of the eth0 interface, the network facing interface of the LoadMaster, in the input field within the Network Side Interface Address dialog box.
3. Press OK.
4. Enter the IP address of the default gateway in the input field of the Default Gateway dialog box.
5. Press OK.
6. Once these are set, a prompt will appear asking to connect to the web interface at the newly configured IP address. In an internet browser enter the IP address of the eth0 entered in Step 2.
Ensure to enter https:// before the IP address.
7. A warning may appear regarding website security certificates. Please click the continue/ignore option.
8. The LoadMaster End User License Agreement screen appears.
9. Please read the license agreement and, if willing to accept the conditions therein, click on the Agree button to proceed.
10. If the machine has shipped with a temporary license, a warning will appear informing that a temporary license has been installed on the machine and for how long the license is valid.
11. Click OK.
12. The Appliance Vitals screen of the LoadMaster should appear.
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.
3.2 Static MAC Addresses Must Be Configured
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.
3.3 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.
3.4 NIC Ordering After Reboot
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.
