    Primary RTX 3080 does not appear in the VM's graphic card dropdown (GPU passthrough)

    in VM Engine (KVM)

    Posted

    So here is the short list:

     

    - My BIOS can see my RTX 3080

    - The RTX 3080 works well because I see terminal when and after the Unraid OS started

    - The Unraid's os can see it within the the terminal after the command lspci -nn 

    - The Dropdown in the VM GPU passthrough section not listed it on the WEB GUI

    - The Tools / System devices not listed the RTX 3080 only the GTX 1650 on the web GUI

    Reason that you're not seeing it is because Unraid has already grabbed it for it's own purposes.  You need to isolate it from the OS (Tools - System Devices) to easily pass it through.  (And set the 1650 to be the primary in the BIOS so that Unraid uses it instead)

     

    Thank you, but the RTX 3080 does not in the list under Tools - System Devices. I can see only the GTX 1650.

    And another question. how can you set (change) the primary GPU in the Bios? I don't remember the settings for it.

    Hi all,

     

    I'm new with Unraid, and I love it, but I have a problem with my primary GPU.

     

    I have a server with 2 GPUS. Primary is the RTX 3080 secondary is a GTX 1650. Unraid starts well without GUI mode, everything is fine, but in the VM's dropdown I can select only the GTX 1650. The RTX 3080 does not appear in the list. --I used the 1st PCIe X16 slot for the RTX 3080 and the card is working well if I connect a monitor directly it, I can see the Unraid's command line messages. 

     

    So I tried to list my devices in the tools / system device but I see only groups to ID 30. IOMMU group 30. BUT...

     

    When I run the lspci -nn from the command line, i see AND I CAN SEE my card with group ID 43.00.0:

     

    43:00.0 VGA compatible controller [0300]: NVIDIA Corporation GA102 [GeForce RTX 3080] [10de:2206] (rev a1)
    43:00.1 Audio device [0403]: NVIDIA Corporation GA102 High Definition Audio Controller [10de:1aef] (rev a1)

    Secondary: GTX 1650
