vSphere Virtual Machine Administration Customizing Guest Operating Systems in the vSphere Web Client When you clone a virtual machine or deploy a virtual machine from a template, you can customize the guest operating system of the virtual machine to change properties such as the computer name, network settings, and license settings. Customizing guest operating systems can help prevent conflicts that can result if virtual machines with identical settings are deployed, such as conflicts due to duplicate computer names. You can specify the customization settings by launching the Guest Customization wizard during the cloning or deployment process. Alternatively, you can create customization specifications, which are customization settings stored in the vCenter Server database. During the cloning or deployment process, you can select a customization specification to apply to the new virtual machine. Use the Customization Specification Manager to manage customization specifications you create with the Guest Customization wizard. Guest Operating System Customization Requirements To customize the guest operating system, you must configure the virtual machine and guest to meet VMware Tools and virtual disk requirements. Other requirements apply, depending on the guest operating system type. VMware Tools Requirements The current version of VMware Tools must be installed on the virtual machine or template to customize the guest operating system during cloning or deployment. Virtual Disk Requirements The guest operating system being customized must be installed on a disk attached as SCSI node 0:0 in the virtual machine configuration. Windows Requirements Customization of Windows guest operating systems requires the following conditions: n Microsoft Sysprep tools must be installed on the vCenter Server system. See Chapter 6, “Installing the Microsoft Sysprep Tool,” on page 101. n The ESXi host that the virtual machine is running on must be 3.5 or later. Guest operating system customization is supported on multiple Windows operating systems. Linux Requirements Customization of Linux guest operating systems requires that Perl is installed in the Linux guest operating system. Guest operating system customization is supported on multiple Linux distributions. Verifying Customization Support for a Guest Operating System To verify customization support for Windows operating systems or Linux distributions and compatible ESXi hosts, see the VMware Compatibility Guide at VMware.com. You can use this online tool to search for the guest operating system and ESXi version. After the tool generates your list, click the guest operating system to see whether guest customization is supported. 44 VMware, Inc.
Create a vCenter Server Application to Generate Computer Names and IP Addresses in the vSphere Web Client As an alternative to entering computer names and IP addresses for virtual NICs when you customize guest operating systems, you can create a custom application and configure it so that vCenter Server can generate the names and addresses. The application can be an arbitrary executable binary or script file appropriate for the corresponding operating system in which vCenter Server is running. After you configure an application and make it available to vCenter Server, each time you initiate a guest operating system customization for a virtual machine, vCenter Server executes the application. The application must comply with the reference XML file in the VMware knowledge base article at http://kb.vmware.com/kb/2007557. Prerequisites Verify that Perl is installed on vCenter Server. Procedure 1 Create the application and save it on the vCenter Server system's local disk. 2 Select a vCenter Server instance in the inventory. 3 Click the Manage tab, click Settings, and click Advanced Settings. 4 Click Edit and enter the configuration parameters for the script. a In the Key text box, type config.guestcust.name-ip-generator.arg1. b In the Value text box, type c:\sample-generate-name-ip.pl and clickAdd. c In the Key text box, type config.guestcust.name-ip-generator.arg2. d In the Value text box, type the path to the script file on the vCenter Server system and click Add. For example, type c:\sample-generate-name-ip.pl. e In the Key text box, type config.guestcust.name-ip-generator.program. f In the Value text box, type c:\perl\bin\perl.exe and click Add. 5 Click OK. Chapter 3 Deploying Virtual Machines in the vSphere Web Client You can select the option to use an application to generate computer names or IP addresses during guest operating system customization.
