Hyper-V

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 Microsoft Hyper-V environment. The VLM has been tested with Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows 8 and Hyper-V 2016.

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 Microsoft Hyper-V virtual machine guest environment for the VLM, at minimum, must include:

2 x virtual processors

2 GB RAM

16 GB virtual hard disk capacity (sparse where possible)

There may be maximum configuration limits imposed by Hyper-V such as maximum RAM per VM, Virtual NICs per VM and so on. For further details regarding the configuration limits imposed by Microsoft Hyper-V, please refer to the relevant Microsoft Hyper-V documentation.

3 Troubleshooting

3.1 Configuring the LoadMaster via the Console

If the LoadMaster does not automatically obtain an IP address using DHCP, or if the user prefers to configure the LoadMaster via the console, then the following configuration steps must be completed before starting the LoadMaster.

1. Login into the LoadMaster via the console using the 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 NIC Types Cannot Be Mixed

If you add new Network Adapters to a VLM then they must be of the same Adapter Type as those already configured on the VLM.

If you install a Network Adapters with a different Adapter Type as those already configured on the VLM the VLM will not recognize the new interface.

3.3 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 Hyper-V documentation.

3.4 Make this VM Highly Available Option is Greyed Out

There is an option in the Virtual Machine Manager called Make this VM highly available. This option is set when the Virtual Machine is placed on a host. Therefore, the option will be grayed out, even when the Virtual Machine is not running. There is a way to work around this problem without having to delete and re-create the Virtual Machine. The Virtual Machine can be migrated. Follow the steps below to do this:

1. Open the Virtual Machine Manager console.

2. Right-click the relevant Virtual Machine that you want to make highly-available and select Migrate.

3. Select the current host from the list for migration.

4. Click Yes to the prompt asking if you want to make the Virtual Machine highly available.

5. The path can be changed if needed. Click Next.

6. Select the network and click Move.

7. Wait for the migration to complete.

3.5 Factory Reset

If you perform a factory reset on the 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 via the console as described in the Configuring the LoadMaster via the Console section.

3.6 Status of Degraded (Integration Services Upgrade Required)

This is a warning message indicating that the LoadMaster software is too old to run on it and can be ignored. Integration services are used when booting to enable Hyper-V to see that the LoadMaster is running. After this point, it is no longer used.
