I now see glorious color on my screen in the form of the fedora installation ui. Thank you so much for the help! Definitely going to need to diff your xml so I can see the changes between the original and the new.

Here is the output of the terminal command. Attached are the diagnostics file and the vbios file. root@:~# cat /proc/iomem 00000000-00000fff : Reserved 00001000-0009dfff : System RAM 0009e000-0009efff : Reserved 0009f000-0009ffff : System RAM 000a0000-000fffff : Reserved 000a0000-000bffff : PCI Bus 0000:00 000e0000-000e3fff : PCI Bus 0000:00 000e4000-000e7fff : PCI Bus 0000:00 000e8000-000ebfff : PCI Bus 0000:00 000ec000-000effff : PCI Bus 0000:00 000f0000-000fffff : PCI Bus 0000:00 000f0000-000fffff : System ROM 00100000-8a4de017 : System RAM 03000000-03a00816 : Kernel code 03c00000-03e4afff : Kernel rodata 04000000-04127f7f : Kernel data 04471000-045fffff : Kernel bss 8a4de018-8a4eb857 : System RAM 8a4eb858-9466a017 : System RAM 9466a018-94690457 : System RAM 94690458-98dfffff : System RAM 98e00000-98e00fff : Reserved 98e01000-9c1fbfff : System RAM 9c1fc000-9da63fff : Reserved 9da64000-9db93fff : ACPI Tables 9db94000-9dd93fff : ACPI Non-volatile Storage 9dd94000-9ec4dfff : Reserved 9ec4e000-9ec4efff : System RAM 9ec4f000-9fffffff : Reserved a0000000-dfffffff : PCI Bus 0000:00 a0000000-b1ffffff : PCI Bus 0000:02 a0000000-afffffff : 0000:02:00.0 a0000000-a18fffff : efifb b0000000-b1ffffff : 0000:02:00.0 b0000000-b1ffffff : vfio-pci b2000000-b30fffff : PCI Bus 0000:02 b2000000-b2ffffff : 0000:02:00.0 b2000000-b2ffffff : vfio-pci b3000000-b307ffff : 0000:02:00.0 b3080000-b3083fff : 0000:02:00.1 b3100000-b31fffff : 0000:00:1f.3 b3200000-b32fffff : PCI Bus 0000:05 b3200000-b3203fff : 0000:05:00.0 b3200000-b3203fff : nvme b3300000-b33fffff : PCI Bus 0000:04 b3300000-b330ffff : 0000:04:00.0 b3300000-b330ffff : r8169 b3310000-b3313fff : 0000:04:00.0 b3400000-b34fffff : PCI Bus 0000:01 b3400000-b3403fff : 0000:01:00.0 b3400000-b3403fff : nvme b3500000-b350ffff : 0000:00:14.0 b3500000-b350ffff : xhci-hcd b3510000-b3513fff : 0000:00:1f.3 b3514000-b3515fff : 0000:00:17.0 b3514000-b3515fff : ahci b3516000-b3517fff : 0000:00:14.2 b3518000-b35180ff : 0000:00:1f.4 b3519000-b35197ff : 0000:00:17.0 b3519000-b35197ff : ahci b351a000-b351a0ff : 0000:00:17.0 b351a000-b351a0ff : ahci b351b000-b351bfff : 0000:00:16.0 b351c000-b351cfff : 0000:00:14.2 b351d000-b351dfff : 0000:00:12.0 b351d000-b351dfff : Intel PCH thermal driver b351e000-b351efff : 0000:00:08.0 e0000000-efffffff : PCI MMCONFIG 0000 [bus 00-ff] e0000000-efffffff : Reserved e0000000-efffffff : pnp 00:07 fc800000-fe7fffff : PCI Bus 0000:00 fd000000-fd69ffff : pnp 00:04 fd6a0000-fd6affff : pnp 00:06 fd6b0000-fd6bffff : pnp 00:06 fd6c0000-fd6cffff : pnp 00:04 fd6d0000-fd6dffff : pnp 00:06 fd6e0000-fd6effff : pnp 00:06 fd6f0000-fdffffff : pnp 00:04 fe000000-fe010fff : Reserved fe010000-fe010fff : 0000:00:1f.5 fe038000-fe038fff : pnp 00:08 fe200000-fe7fffff : pnp 00:04 fec00000-fec00fff : Reserved fec00000-fec003ff : IOAPIC 0 fed00000-fed03fff : Reserved fed00000-fed003ff : HPET 0 fed00000-fed003ff : PNP0103:00 fed10000-fed17fff : pnp 00:07 fed18000-fed18fff : pnp 00:07 fed19000-fed19fff : pnp 00:07 fed20000-fed3ffff : pnp 00:07 fed40000-fed44fff : MSFT0101:00 fed45000-fed8ffff : pnp 00:07 fed91000-fed91fff : dmar0 fee00000-fee00fff : Local APIC fee00000-fee00fff : Reserved ff000000-ffffffff : Reserved ff000000-ffffffff : pnp 00:04 100000000-85dffffff : System RAM 85e000000-85fffffff : RAM buffer corsair-diagnostics-20210912-1839.zip vbios.zip

Hi @ghost82, thanks for responding. Long week so I didn't get a chance to revisit your suggestions until today. I moved the gpu to a lower slot and bound it to vfio at boot using the unraid gui (hoping this is what you were talking about for step 1). I also dumped vbios after a lot of googling on how to do so. Still, I am seeing the same blank screen as before. Here are the vfio logs followed by the logs for the fedora vm I am trying to spin up. Looking at the logs I see a lot of these "device or resource busy" warnings.

Hi all! I am testing out unraid as a solution for storage / virtualization / tinkering. I am trying to get a fedora VM w/ my RTX 3080 to output via the displayport connection to my screen. I think something is happening because when my VM starts up and the monitor is off it will turn on as if something is being outputted. However, the screen stays black. When I use VNC instead of the GPU passthrough, I am able to see the fedora UI. The computer works fine when I am booting from bare metal. I did some troubleshooting already from stuff on this forum and from external guides and I realized that I hadn't set up IOMMU, but that should be squared away now. I seem to be pretty stuck on this issue though. Below are my PC specs and my VM xml along with the only suspect item in the logs I noticed. Happy to provide whatever other debug info is helpful and I appreciate all responses. Thanks!
