December 3, 20187 yr Ok i know there are TONS of questions about this and i have followed just about every forum and Video that i can find and i am still unable to get the GPU to passthrough correctly. I am currently running a Ryzen 2700x on the B-450Strix MOBO with a Asus 750TI in the first x16 slot. Im trying to pass this through to a Windows 10 VM with the following XML: <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' id='5'> <name>Win-VM</name>

GPU directly. I was able to get this passed through just fine in my older system ( intel based) with needing to dump the bios. I have stubbed the GPU but it didnt make any difference. All i get is a Black screen Any help will be appreciated.
December 3, 20187 yr If you are using UEFI Boot with unRAID you may get a black screen. Try Legacy boot.
December 3, 20187 yr Author I would assume this would mean im booting Legacy ( havent checked the BIOS yet) After i posted this i was able to get into the machine via RDP and notice im getting a code 43 error on the device Edited December 3, 20187 yr by 08deanr
December 3, 20187 yr I never had the code 43, I passthru a GTX 1070 with a 2700x system. Passing thru a bios file and everything.
December 3, 20187 yr Author do you have the GPU stubbed in the syslinx config? kernel /bzimage append vfio-pci.ids=1106:3483 vfio-pci.ids=1022:43d5 vfio-pci.ids=10de:1380 pcie_acs_override=downstream initrd=/bzroot

December 5, 20187 yr Gigabyte gaming 5 ax370 r7 2700x EVGA GTX 2070 32 GB Ram. Also a usb 3.1 card for my vms. 22 TB of storage. My VM is on a nvme drive thats passed through.

December 5, 20187 yr You can try with a seabios based VM. The easiest way is to create a Windows 7 in unraid web console which will use seabios by default. I get black screen on my intel system if nvidia card is primary with UEFI. I believe its because host boot "touches" UEFI but the seabios is left intact.
