Using sysprep to initialize a Windows virtual machine has no effect

[yule-sun]

Affected version

In the ovirt4.4.8.6 environment, I installed a Windows virtual machine and used sysprep /oobe /shutdown to shut it down. Then I used this virtual machine to create a template, and then used the template to create a virtual machine.After using the sysprep function to start the virtual machine, the configuration of the virtual machine did not change.

• oVirt Engine: ovirt-engine-4.4.8.6-1.el8.noarch
• Host OS Variant: ovirt-host-4.4.9-2.el8.x86_64
• VDSM version: vdsm-4.40.100.2-1.el8.x86_64
