Hi,
I have been trying to use unraid as a desktop using GPU passthrough to use my vms. The vms work fine using VNC, I have been successfully installing windows 10/ubuntu 19.10 vms using that. However, I keep getting no signal to my monitor whenever I try to start a vm using gpu passthrough.
Here is my setup:
- Asus ROG Strix 470-f Gaming motherboard.
- AMD Ryzen 7 2700x
- Nvidia GT 520 in PCIE 1 slot (used as my main graphics card, the unraid GUI displays on the monitor connected to this card
- Nvidia GTX 1080ti in PCIE 2 slot (the one I want to passthrough, the connected monitor gives a black screen)
- 16GB RAM
I do not have any integrated graphics, this is why I put my old GT 520 in this computer, so that it is used for unraid and I have the 1080 free for passthrough. AMD Vi is enabled in the bios.
Here is what I tried:
- ACS Override did not solve the issue
- The problem happens weather I create the VM with OVMF or SEABios
- I dumped my 1080 rom using SpaceInvader's tutorial, didn't solve
- I tried setting the VM to a Q35 machine
Attached are the syslog and vms xml.
Thank you for your help.
