pcie passthrough

Hi, I want to replace an old WinXP test machine with an Proxmox VM. The software is very specific and not compatible with any newer OS and there are several PCIe cards that are used. So Proxmox and a modern HW seemed to be a promissing solution for that problem. I was able to activate PCIe...

I'm trying to passthrough 2 GPUs to the same VM without luck. If I boot it with only one of them configured, the VM boots and everything works as expected. But when I configure both at the same time, the VM doesn't output anything nor collects logs (checked multiple logs inside `/var/log` and...

Hi i’m trying to setup in Proxmox with 2 U.2 SSD drives in a Windows Server 2022 Stantard VM to been used as disaster recovery offsite backup to be taken away once a week (one installed in a detachable tray to be swapped with a second drive) and i’m having problem trying to make hotswap work on...

Hello, I am having a bit of trouble working out what to do with a newly installed PCIe SATA controller in my Proxmox VE. I have installed this card and it connects to 2x HDD hot swap bays on the front of my box. I have confirmed it is working, proxmox sees a drive I have in the bay and lists it...

Hi Mates! My AMD GPU can't be accessed after VM poweroff. When I first turn on the host, start VM, the GPU which is passthroughed can work normally ( for me the GPU is 5700XT), and I can also see the VM screen on my monitor. But after I shutdown the VM, I would see this error: vfio-pci...

New Proxmox user here. I have a TrueNAS Core 13.0-U5.2 VM. It is installed in a WD Blue SSD named VMs_CT_Main. I have passed through a Dell H310 HBA to it with 8 HDDs attached. Below is the config of the TrueNAS VM. kristian@pve:~$ sudo qm config 100 [sudo] password for kristian: agent: 1...

After the default upgrade (first within PVE 7.4 and now with PVE 8), the as default installed Kernel 6.x prevents my VM with a GPU passthrough to boot properly. Within the dmesg log, the error [DMA Write NO_PASID] Request device [c7:00.0] fault addr 0x27af3000 [fault reason 0x05] PTE Write...

On my proxmox server (R7 5700X, 48GB RAM, Proxmox 7.4, Kernel: 6.2.11-2-pve) I have a vm running Arch Linux for gaming with a RX 6700 XT passed through to it. In most games I see performance within margin of error of running bare metal, but some games, most notably Sea of Thieves and Forza...

I've been trying for weeks to get GPU passthrough to work in a Windows 10 guest vm in Proxmox. I'm having trouble troubleshooting, or even understanding what I'm doing, since I feel like I've been following multiple guides at once and implementing any/all advice I find on forums. A few weeks...

I've got a proxmox 7.4-3 server running an i7-5820K on a ASRock x99 Taichi, with a Gigabyte GT 710. The GPU works fine (I can use it to edit BIOS settings when I boot) . I've followed the steps mentioned in both this reddit post and this one. I end up getting error 43 and no display sent out the...

Hello, I am having an issue running an Nvidia RTX-2070 Super and an LSI-9211-8i at the same time on separate VMs. I can run them independently without issue, but the second I try to run their VMs at the same time I get the QEMU Exit Code 1 and it fails to start. These devices are not in the...

Hello! I have been anticipating the Ryzen 7000 series 3D V-Cache chips for some time now and am planning to build a new system with one soon. If the situation I detail below performs as I hope, I would like to use it in a Proxmox system with a Windows gaming VM. Now that the 7950X3D & 7900X3D...

Good afternoon everyone. I'm trying to do a PCIE passthrough on an Nvidia GT 630 graphics card. I'm pretty stuck because I've tried a lot of options by following forums and youtube videos. None work for me. The fact is that I tryied the same operation with a 3060 TI that they lent me for the...

Hello proxmox users! quick question about using nvme m.2 drives. I have a pcie to m.2 cardholder in my server with a total of 4 drives. I need a vm with a lot of speed. In terms of performance, is it better to pass through the whole card or is there no loss when creating virtual disks?

Hallo, ich habe einen usecase bei dem ich auf einem lxc pytorch ausführen möchte um ein neuronales Netz zu trainieren. Dafür würde ich gerne 1-2 AMD Grafikkarten in den lxc container durchreichen wollen um auf diesem rocm zu nutzen. Hat jemand den gleichen usecase bzw. schon mal für rocm eine...

Hi Proxmox community! I´m having trouble trying to passthrough the use of a GPU to a Win10 VM. I´ve followed several guides, some posted on this forum and what is posted on Proxmox VE wiki along with in more general terms of how passthrough is performed from host to VM. I´m running Proxmox VE...

Hi I'm new to promox and virtualization. I followed the guides that I could find for pcie passthrough and I don't seem to make it to work. I get the bellow: [ 0.012286] ACPI: DMAR 0x00000000C9EC9000 0000A8 (v01 INTEL SKL 00000001 INTL 00000001) [ 0.012324] ACPI: Reserving DMAR...

Hi, I am trying to passthrough a Dell H330 card in my Dell T630 server to my TrueNas Scale VM, but cannot get it working. I got this far: IOMMU enabled, driver is blacklisted, but no luck, looks like my BIOS won't allow this. Anyone managed to get this working on a 13th gen Dell server? What...

Hi, are there any issues with passing through a Sangoma D100 PCIe Card to a VM? It's a VoIP Transcoding card, I can't find and documented cases of it being passed-through on PVE. We want to use it on a Centos 7 VM with PVE 7.2-7. I don't want SR-IOV passthrough...
