Search results for query: passthrough GPU

If all you want to do is (whole) GPU passthrough to a VM then you don't need this particular GPU (with its fancy SR-IOV features) and you can chose from several (cheaper) known-to-work-with-passthrough (consumer) GPUs.

well, sr-iov is the 'pci standard' way to do multiple vgpus on a single pci card. nvidia takes a slightly different approach (you have to "activate" a profile on the virtual function and need a specialized driver) for normal passthrough, nothing is changing here, so if you're not interested in...

Hi, I have a very similar problem. I switched to new Mainboard and CPU and now GPU passthrough does not work, whereas it works without any problems with a network card and also a TV card. GPU passthrough worked without any problems with the old hardware. As I am very impatient, waiting is not...

Is there an update to get WSL working with GPU passthrough? (iGPU Intel UHD770 on 13900T)

...create a hookscript that can do the following: If VM1 is shut down, then start VM2. AND If VM2 is shut down, then start VM1. This way, both VMs could share the single passthrough GPU. Are there any code examples for Proxmox hookscripts? And do you think what I'm trying to do is...

Hi Dominik, thanks a lot for the detailed suggestions — we followed up on all of them and here is a complete update. --- 1) MMIO size (next power of two above BAR2) You were absolutely right about the power-of-two requirement. On the host, the B300 reports: - BAR2 = 512 GB - plus additional...

Hi Dominik, thanks for the follow-up — happy to provide more details. Below is exactly how we increased MMIO, plus the requested host lspci output and full VM config. --- 1) How MMIO was increased We tested multiple MMIO sizes using the OVMF fw_cfg method, always with the VM fully powered...

Hello everyone, I’m trying to understand the correct expectations and support boundaries for GPU passthrough on DGX / HGX B300 platforms when using Proxmox (KVM/QEMU). Environment: - Proxmox VE (9.1.4 ) - Machine type: q35 - BIOS: OVMF (UEFI) - IOMMU enabled, vfio-pci used - Host platform...

I decided to give up with the potential 9.1 issues and formatted the boot disk, reinstalled with a Proxmox 8.4 image, restored the VMs and started attempting this again. I was still getting the same error on 8.4 with the 6.8 kernel. I have another machine with a 1650 Super that is passing...

Im new to proxmox, this week actually but I need this too. I dont how much you've worked on this but I currently have mine set up for bazzite with nvidia 5080 and tiny win 11. I attach the gpu to bazzite with windows shutdown and everything works. when I need windows I shut down bazzite...

I was unaware of official proxmox documentation existed to be honest. When I get home from work I will read about GPU pass through. I have searched the forum, however I haven't found anyone who's having the same issue as me regarding this.

Hi, @myron1 Have you read the official Proxmox documentation on this subject first? Have you searched this forum? Just yesterday there was a thread about GPU passthrough.

Hello! I would like to start with I am very new to proxmox and am currently trying to get into it. However, I have been having a very hard time trying to enable GPU passthrough so I can have my own local AI. I have followed the guide below and am still having trouble with it...

mine definitely requires both PCI devices to be passed through, is yours the 4 bay or 2 bay?

I just created a custom BIOS for WTR 5700U/5825U. All PSP components are updated to AGESA 1.0.1.1C and GOP is updated to 2.24. It does fix the throttling issue for me, actually there is only one PCI device to pass (the second one), and the 2 disks are properly detected. All BIOS parameters are...

Sorry I was working double time this week is everything sorted .. Did you get the file from me .. :) Cheers :)

You pass-through what you need and leave what you need on the host (!) out of the vfio-pci configuration. Should be as easy as that, basically. That means you define your added Intel A310 with it's PCI-ID for vfio-pci, while you just do nothing about the server internal graphics. See chapter...

Yes. I cannot guarantee that there is no risk, as passing real hardware to a VM can interfere with the host. But without the pcie_acs_override, IOMMU should protect you from devices secretly communicating (and reading memory).

One last question. This only applies if the ACS patch is active, right? If you passthrough a GPU to a VM using the standard IOMMU groups (without patching), then there's no risk. Right?

Hello, I have finally made it work with following 140.conf (please note there is no args, with which it didn't start for me and also the display is set to default: acpi: 1 bios: ovmf boot: order=scsi0;ide2;net0 cores: 4 cpu: host efidisk0...
