= Generalizing a Windows VM image
|
|
|
|
You can generalize a Windows operating system image to remove all system-specific configuration data before you use the image to create a new virtual machine (VM).
|
|
|
|
Before generalizing the VM, you must ensure the `sysprep` tool cannot detect an answer file after the unattended Windows installation.
|
|
|
|
.Prerequisites
|
|
|
|
* A running Windows VM with the QEMU guest agent installed.
|
|
|
|
.Procedure
|
|
|
|
. In the {product-title} console, click *Virtualization* -> *VirtualMachines*.
|
|
. Select a Windows VM to open the *VirtualMachine details* page.
|
|
. Click *Configuration* -> *Disks*.
|
|
. Click the Options menu {kebab} beside the `sysprep` disk and select *Detach*.
|
|
. Click *Detach*.
|
|
. Rename `C:\Windows\Panther\unattend.xml` to avoid detection by the `sysprep` tool.
|
|
|
|
. Start the `sysprep` program by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
%WINDIR%\System32\Sysprep\sysprep.exe /generalize /shutdown /oobe /mode:vm
|
|
----
|
|
. After the `sysprep` tool completes, the Windows VM shuts down. The disk image of the VM is now available to use as an installation image for Windows VMs.
|
|
|
|
You can now specialize the VM.
