<strong>vSphere</strong> <strong>Virtual</strong> <strong>Machine</strong> <strong>Administration</strong><br />
Customize Windows During Cloning or Deployment in the <strong>vSphere</strong> Web Client<br />
You can customize Windows guest operating systems for the virtual machine when you deploy a new virtual<br />
machine from a template or clone an existing virtual machine. Customizing the guest helps prevent conflicts<br />
that can result if virtual machines with identical settings are deployed, such as duplicate computer names.<br />
You can prevent Windows from assigning new virtual machines or templates with the same Security IDs (SIDs)<br />
as the original virtual machine. Duplicate SIDs do not cause problems when the computers are part of a domain<br />
and only domain user accounts are used. However, if the computers are part of a Workgroup or local user<br />
accounts are used, duplicate SIDs can compromise file access controls. For more information, see the<br />
documentation for your Microsoft Windows operating system.<br />
IMPORTANT The default administrator password is not preserved for Windows Server 2008 after customization.<br />
During customization, the Windows Sysprep utility deletes and recreates the administrator account on<br />
Windows Server 2008. You must reset the administrator password when the virtual machine starts the first<br />
time after customization.<br />
Prerequisites<br />
Verify that all requirements for customization are met. See “Guest Operating System Customization<br />
Requirements,” on page 79.<br />
Start the Guest Customization wizard when you clone a virtual machine or deploy from a template. See “Clone<br />
a <strong>Virtual</strong> <strong>Machine</strong> in the <strong>vSphere</strong> Client,” on page 68 or “Deploy a <strong>Virtual</strong> <strong>Machine</strong> from a Template in the<br />
<strong>vSphere</strong> Client,” on page 74.<br />
Procedure<br />
1 On the Select clone options page of the Clone Existing <strong>Virtual</strong> <strong>Machine</strong> wizard, select Customize the<br />
operating system and click Next.<br />
2 Type the virtual machine owner’s name and organization and click Next.<br />
3 Enter the guest operating system's computer name.<br />
The operating system uses this name to identify itself on the network. On Linux systems, it is called the<br />
host name.<br />
Option Action<br />
Enter a name a Type a name.<br />
The name can contain alphanumeric characters and the hyphen (-)<br />
character. It cannot contain periods (.) or blank spaces and cannot be<br />
made up of digits only. Names are not case-sensitive.<br />
b (Optional) To ensure that the name is unique, select Append a numeric<br />
value to ensure uniqueness. This action appends a hyphen followed by<br />
a numeric value to the virtual machine name. The name is truncated if<br />
it exceeds 63 characters when combined with the numeric value.<br />
Use the virtual machine name The computer name that vCenter Server creates is identical to the name of<br />
the virtual machine on which the guest operating system is running. If the<br />
name exceeds 63 characters, it is truncated.<br />
Enter a name in the Clone/Deploy<br />
wizard<br />
Generate a name using the custom<br />
application configured with vCenter<br />
Server<br />
The <strong>vSphere</strong> Client prompts you to enter a name after the cloning or<br />
deployment is complete.<br />
Enter a parameter that can be passed to the custom application.<br />
