Hi,
I have been able to use a tiny11 23h2 ISO image from this link https://archive.org/details/tiny11-2311 and create a vm. As next steps I am trying to passthrough my rtx 3070ti graphics card to the vm. I have been unsuccessful so far and I have tried to follow through several YouTube videos and tutorials. The most famous tutorial on reddit seems to be quite outdated. It can be found here, https://www.reddit.com/r/homelab/comments/b5xpua/the_ultimate_beginners_guide_to_gpu_passthrough/.
The Proxmox 8.4 was installed using UEFI boot. The legacy boot option for bios on the Dell Precision T5810 is pretty bad. I kept on getting 'boot drive not found' error and so I installed proxmox using uefi. Below are all the hardware specs of my system:
CPU Model: Intel CPU Xeon 2695 v4
Motherboard: YRTRT AL3610
Graphics Card 1: RTX 3070 Ti
Graphics Card 2: Geforce Gtx 745
The CPU and Motherboard both support iommu.
Since this is the newer version of proxmox I have added the following in the
The output above is not complete. The last line repeats with different iommu group numbers and hex codes and goes to 54.
Any help in configuring the gpu passthrough for the windows 11 vm would be highly appreciated. Ideally I would want to passthrough only the RTX 3070 Ti to the windows vm and use the GTX 745 for the proxmox ui. So any custom blacklist command would be highly appreciated as well.
Cheers
