Protheus Posted December 11, 2020 Share Posted December 11, 2020 (edited) Hi, my Unraid-Server is now on and productive (thanks for the recent help). But now i thought "why not place my plex VM onto this?" (please, i don't want to discus plex vm vs. plex docker) So i migrated the VM from esxi to my unraid. Then i said "passthrough my old NVidia GTX 560 Ti (for transcoding). But if i boot the VM the screen remains black. If i switch to VNC output the VM is booting and plex is working.

more threads to this (but mostly with more newer grafics cards) I hope i can find some help.

Protheus Posted January 1, 2021 Author Share Posted January 1, 2021 UPDATE: OK, since i thought, a GTX 560 ti is a little bit weak for transcoding i bought a new Gigabyte GTX 1650 D6 OC 4G. But the Problem still exists. I've looked the two relevant SpaceInvaderOne Videos and read various Posts (most relevant): https://mediaserver8.blogspot.com/2020/07/problems-passing-through-gpu-to-unraid.html I've tried every possible Variation/Solution: - Switched the GPU from PCIe-Slot1 to PCIe-Slot2 - Activated PCIe ACS Override Downstream/Multifunction/Both (my Bios have no clear Option for this) (Now it looks like that) Yes, i passed through all of the device Parts I've created 4 VMs in various Configurations OVMF-i44fx ovmf-q35 seabios-i440fx seabios-q35 (XML attached): Plex-seabios-q35.xmlPlex-seabios-i440fx.xmlPlex-OVMF-q35.xmlPlex-OVMF-i440fx.xml - I've set the multifunction Parameter in the XML and corrected the BUS/SLOT/FUNCTION - I've downloaded the vbios (and corrected it like descibed in SIOs Video) and tried it with and without ... but nothing works. Can someone show me my tiny little mistake i did? It cant be that hard to pass through a modern GPU. Here is my System: M/B: MSI Z97 GAMING 7 (MS-7916) Version 1.0 - s/n: To be filled by O.E.M. BIOS: American Megatrends Inc. Version V1.12.

Protheus Posted January 3, 2021 Author Share Posted January 3, 2021 UPDATE 2: i found a workaround for myself -> Update to Unraid 6.9 RC2 After the Upgrade i've got an Output. After that i struggled a little bit with boot from ISO (GPU passthrough blocked boot from ISO with a OVMF VM). So i switched to VNC -> booted Veeam Linux Recovery ISO -> Recovered my ESXi Plex VM (Bare Metal) -> Switched to GPU Pasthrough -> and BINGO - Its working After some linux driver improvements and nvenc patching my plex VM can hardware-transcode (that was one of the Goals) So conclusion: - The whole migration project came with many running (between my rooms), shouting and reading. But in the end it worked. - After the unraid upgrade the web-gui is fast as hell and really responsive. - I think Unraid is the best NAS System for my needs and i will stay with it (bought Pro) Thanks to limetech for this nice piece of software, SpaceInvaderOne for his really understandable Videos (without that i could never realize this) and the community (Addons and some hints) Greetings Quote Link to comment
