Some of the menus in the "Nvidia control panel" missing & kvm hidden not working

[JeffSuperb]

I have a Windows 11 VM.I found some items in the Nvidia control panel were missing, and then I found this 

 

this post ask me to add in the templet

<kvm>
   <hidden state='on'/>
</kvm>

 

But after I added this section to my VM XML, the windows no longer start. When I start Windows, the screen is black, and after ~2 minutes, the VM stop. If I go to log, this is the error I see. 
 

2023-10-17T10:49:16.378630Z qemu-system-x86_64: terminating on signal 15 from pid 15235 (/usr/sbin/libvirtd)

 

 

Here is the VM XML I use after adding kvm hidden.

 <features>
    <acpi/>
    <apic/>
    <hyperv mode='custom'>
      <relaxed state='on'/>
      <vapic state='on'/>
      <spinlocks state='on' retries='8191'/>
      <vendor_id state='on' value='other'/>
    </hyperv>
    <kvm>
       <hidden state='on'/>
    </kvm>
  </features>

 

 

 I also tried to add vbios to my GPU, but it is not working. I tested both my GTX 960 and RTX 2080TI, and the same thing for both cards. (Nvidia menu item missing; if add KVM hidden, then Windows does not start.)

 

Does any one have any clue what else I can try?

I have the same problem

This does work if you also change the 

<vendor_id state='on' value='other'/>

into 

<vendor_id state='on' value='randomid'/>
