5 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 VMware ESX or ESXi hypervisor environment. The VLM is has been tested with VMware ESX 4.0, 4.1, 5.0 and 5.1, vcenter Server 5.5, VMware ESXi 4.0, 4.1, 5.0, 5.1 and 5.5 and vsphere 4.0, 5.0 and 5.5. There are several different versions of the VLM available. Full details of the currently supported versions are available on our website: The VMware virtual machine guest environment for the VLM, at minimum, must include: 2 x virtual CPUs (reserve 2 GHz) 1 GB RAM 32 GB disk space There may be maximum configuration limits imposed by VMware such as maximum RAM per VM, Virtual NICs per VM etc. For further details regarding the configuration limits imposed by VMware, please refer to the relevant VMware documentation.

6 2 Best Practices Some best practices to be aware of before deploying a LoadMaster on VMware are below: Configure a load balancing port group for the relevant VLAN to avoid port flooding Use the E1000 network adapter type when deploying the VLM Figure 2-1: Security Tab The Security Policy Forged Transmit on the Portgroup should be 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. Figure 2-2: NIC Teaming Tab 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. Copyright KEMP Technologies, Inc.

7 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. Download the OVF File The VLM is packaged with an.ovf file for ease of deployment. This file can be freely downloaded from KEMP Technologies for a 30 day evaluation period. To download the VLM please follow the following instructions. 1. Log on to 2. Within the Select the hypervisor platform section, select the option for VMware ESX, ESXi and vsphere. 3. Click on the Download OVF button. 4. Read the end user agreement. 5. If you wish to continue, select your country from the drop-down list. 6. Click on the Agree button. 7. Download the ovf zip file. 8. Unzip the contents of the file to an accessible location. Deploy the OVF File To deploy the VLM we initiate a Deploy OVF Template wizard which gathers all the information required to correctly deploy the VLM. 1. Open the VMware vsphere client. 2. Select the correct Resource Pool within which you wish to install the VLM. 3. Select the File > Deploy OVF Template menu option, this initiates the Deploy OVF Template wizard. 4. Within the Source screen, click on the Browse button and select the downloaded file. Copyright KEMP Technologies, Inc. All Rights Reserved. Page 7 / 22

19 4 Troubleshooting 4.1 Cannot access the Web User Interface If a connection to the WUI cannot be established, network settings can be configured via the console view. 1. Login into the VLM via the console using the settings: lb100 login: bal Password: 1fourall Figure 4-1: Enter IP address 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 field and press Enter on the keyboard. Figure 4-2: Enter default gateway address 3. Enter the IP address of the Default Gateway. Copyright KEMP Technologies, Inc. All Rights Reserved. Page 19 / 22

20 Figure 4-3: Nameserver IP addresses 4. Enter a space-separated list of nameserver IP addresses. 5. A message will appear asking to continue licensing via the WUI. Try to access the IP address via a web browser. Ensure to enter before the IP address. 6. Contact the local KEMP Customer Services Representative for further support if needed. 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 via 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 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 Section 4.1. VMware Tools The VLM does not support integration with VMware Tools. However, the NIC device drivers that are part of VMware Tools have been integrated with the VLM which, for many users, negates the need for using VMware Tools. 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. Copyright KEMP Technologies, Inc. All Rights Reserved. Page 20 / 22
