  • Anyone succesful with Nvidia passthrough 6.10.0-rc2 ?

    • Minor

    I have a fresh system and fresh unraid installation.

    MSI B560M-A PRO with i3-10105, RTX 3070.

    [10de:2484] 01:00.0 VGA compatible controller: NVIDIA Corporation GA104 [GeForce RTX 3070] (rev a1)

    [10de:228b] 01:00.1 Audio device: NVIDIA Corporation GA104 High Definition Audio Controller (rev a1)

    VFIO Binding looks succesful in the log: Successfully bound the device 

    VT-D in bios enabled.

     

    I tried Windows 10 about 8 installations with Q35 5.0 up to 6.1 and i440fx from 5.0 up to 6.1, using VNC primary and Nvidia secondary.

     

    The onboard NIC is only recognized with Q35 6.0, nothing else. Later then upgrading 6.1 keeps the NIC alive. Fresh 6.1 installation has no network card and the RTX GPU is not recognized as well. With 6.0 i can install the Nvidia driver.

     

    When i then remove VNC as primary GPU the screen stays black, does not boot without any error message.

     

    Was anyone succesful yet ? My goal is to achieve a windows machine with MadVR behind Kodi as Media Player.

     

    *update* 

    i installed a new machine with Q35 6.0 and windows 11 instead of 10. Succesful with installing network drivers virtio and nvidia card, but after removing the vnc and using nvidia as primary just blank screen.

    do you use a vbios file?

    Two weeks I ago I was also struggling with Nvidia passthrough. Changed Unraid Boot from Uefi to legacy setup Vms completely new etc.

    Got always stuck in Tiano Bios logo. Seems like the GPU Output got frozen on the bootup of the vm. 

    SO startet from scratch with Unraid Boot in Legacy Onboard Gpu enabled on MSI Boards its called IGPU Multimonitor I guess. Installed everything with vnc on first and gpu second and a vbios File. Plugged the Monitor into HDMI because DP just shows up when windows is booted.

    i tried with and without vbios file. i did not go back to legacy bios, but bios setting is using igpu to have the dedicated gpu free. using hdmi as tv & projector need hdmi.

    you need to use vbios I think. For me its only working with vbios. I'm not sure if Unraid legacy boot is needed but for me its working without uefi

    I'm currently having the same issues with two servers on 6.10.0-RC2 with this same motherboard. I've tried just about everything. 


    MSI B560M-A PRO with i3-10100, Radeon RX580.

    and

    MSI B560M-A PRO with i5-11500, RTX 3070.

    I briefly got the RX580 to passthrough to Windows 11 VM (Q35-6.1) with vbios (that I dumped). I installed the gpu drivers and then booted the server, legacy bios, with proper vfio binding and the vm displayed out via the gpu. I then shutdown because my keyboard passthrough wasn't working, changed usb bindings, and then the problems struck. I haven't been able to get it to passthrough since.

     

    I haven't gotten the server with the RTX 3070 to passthrough at all. 
     

    I also haven't been able to get either to passthrough via a Windows 10 VM.


    Accessing the Windows 11 VM from Windows Remote Desktop on the RX580 server shows the GPU currently not being recognized at all in Device Manager.

    Been working for me since I updated to 6.10rc2, ASUS motherboard using UEFI boot with a 1080 Ti passed to a Windows 11 VM. No issues.

    may you share more details, please ? fresh created machine with 6.10rc2 or from previous version ? Which machine type ? 1080ti as the only, primary gpu in that vm ?

    Was a Windows 10 VM I've had for a while, update to 6.10rc2 then added the virtual TPM and upgraded to Windows 11.

    1080Ti is the only GPU in the VM. I use the Intel iGPU for Plex transcoding in Unraid.

     

    I've also done some tweaks manually in the XML over time to make for a better gaming VM based on articles I've read online.

     

    I've attached my VM XML here if it helps you.
