Ubuntu VM shows black screen with passthrough primary Nvidia card

Hi guys,

   I have had this working for over a year but I had to change the amount of RAM available to my VM and that just borked my setup. Now I cant see the video output from my server. Although I can get my Ubuntu VM to show up fine in VNC and a Windows Machine is showing up on my monitors using the same graphics card.

I am passing the same vbios info, and here is the relevant section of that in my config:

<hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x08' slot='0x00' function='0x0'/>
      </source>
      <rom file='/mnt/disks/M2Drive/vBios/GTX1070.dump'/>
      <address type='pci' domain='0x0000' bus='0x05' slot='0x00' function='0x0' multifunction='on'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x08' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x05' slot='0x00' function='0x1'/>
    </hostdev>

In the system log, I am also seeing the following error:

Nov  1 00:14:18 Tower kernel: vfio-pci 0000:08:00.0: vfio_ecap_init: hiding ecap 0x19@0x900

I am running Unraid version 6.11.1.

Does anyone have any suggestions on how I can get my Ubuntu VM to show up on my monitors again?
