October 28, 20196 yr Hi, I have a Asrock X570M and a AMD 2700X. I'm having issues passing through my RX580 to a VM. I enabled IOMMU in the BIOS to see the groups and was successfully able to pass through a PCIe USB Controller to a Windows VM but the RX580 doesn't show up in the list of devices in the VM settings. I double checked the Syslinux configuration to make sure the devices IDs are correct. I currently have a GTX 710 in the first PCIe slot and the AMD 580 in the third slot. I can remove the GTX 710 if needed. Are you allow to pass though the primary GPU device to a VM if there's only one video card in the system? Any help would be greatly appreciated. Thanks! David
October 28, 20196 yr I had to stub my rx 570 from the system for it to work. If i didnt all i got was black screens from the VM.

What do you mean by 'stub' your video card. My current config is: Quote default menu.c32 menu title Lime Technology, Inc. prompt 0 timeout 50 label Unraid OS menu default kernel /bzimage append initrd=/bzroot vfio-pci.ids=1002:67df,1002:aaf0,1912:0014 label Unraid OS GUI Mode kernel /bzimage append initrd=/bzroot,/bzroot-gui label Unraid OS Safe Mode (no plugins, no GUI) kernel /bzimage append initrd=/bzroot unraidsafemode label Unraid OS GUI Safe Mode (no plugins) kernel /bzimage append initrd=/bzroot,/bzroot-gui unraidsafemode label Memtest86+ kernel /memtest The first two ids are my RTX 580 and the hdmi audio.

David Looks like you already got it done. Well i run my server in legacy mode so you can try that. UEFI boot mode never allowed my GPUs to work.

Well I'm an idiot 🙂 I didn't see the RX580 under PCI devices but it was listed in the drop-down of the Graphics Card setting. Thanks again for the help! Edited October 28, 20196 yr by davidst95
