[6.9.0 Beta 30] Unable to pass through a video card in the VM form editor

After changing the VNC port to the P2000, I edited the XML and removed this block

    <graphics type='vnc' port='-1' autoport='yes' websocket='-1' listen='0.0.0.0' keymap='en-us'>
      <listen type='address' address='0.0.0.0'/>
    </graphics>
    <video>
      <model type='cirrus' vram='16384' heads='1' primary='yes'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </video>

I then saved it and edited the VM again and switched it to the form editor. It still had VNC listed, probably by default. I changed it to the P2000 again and the change stuck.

I can confirm that I see the same behaviour, on both of my Unraid systems running 6.9.0 beta 30. Was also able to fix using the same workaround.

I am happy I found this post then I can stop pulling my hair out.

Thanks for the suggested workaround.  

Fixed in RC1 on my system
