Soulplayer Posted January 6, 2023 Share Posted January 6, 2023 Hello, I've been using Unraid for about a month now and I have a small question: Do you need to unplug the HDMI cables from the GPU when booting up the server each time or is there a trick that I can use? If I leave them in I cannot passtrough my GPU because it is already in use by unraid (basic console screen). Thank you! Quote Link to comment
Solution ghost82 Posted January 6, 2023 Solution Share Posted January 6, 2023 It should be possible to leave the hdmi plugged in and: 1. bind to vfio the gpu (both audio, video and usb controller parts, if any) 2. if booting unraid with efi, prevent efifb to attach to the gpu (video=efifb:off in syslinux config) 1 Quote Link to comment
Soulplayer Posted January 6, 2023 Author Share Posted January 6, 2023 (edited) I think I'm botting using UEFI? I changed it to the following: label Unraid OS menu default kernel /bzimage append isolcpus=4-11,16-23 pcie_acs_override=downstream,multifunction initrd=/bzroot,video=efifb:off I think I already binded everything since I needed to do that for passing the card :).

ghost82 Posted January 6, 2023 Share Posted January 6, 2023 (edited) Save diagnostics after plugging hdmi cable, booting unraid and running the vm; from your description you will have a black screen. Stop the vm and save diagnostics. Attach the zip here. Edited January 6, 2023 by ghost82 Quote Link to comment
Soulplayer Posted January 6, 2023 Author Share Posted January 6, 2023 I made an error using Syslinux (added video after /bzroot!). The following works perfectly label Unraid OS menu default kernel /bzimage append isolcpus=4-11,16-23 pcie_acs_override=downstream,multifunction video=efifb:off initrd=/bzroot thank you for the tip!
