vfio-pci

Hi again, I am still tinkering with the project of a TrueNAS VM on PVE 8.1.4. using a HP DL380 G10 with a PCIe/NVMe/U2 riser card and cage. I already posted here with not much success before getting some more info at the TrueNAS forums over here. It turned out that some people there would...

Hello, I am attempting to pass through 2 NVMe drives to two different VMs. They are on an Asus bifurcation card with a total of 4 m.2 slots, all of which are populated. My BIOS has the PCIe slot set to x4x4x4x4 and all of the drives are seen correctly in Proxmox. Hardware is listed at the...

Hi, I have been reading about vhost-user and specifically vhost-user-gpu, which is used alongside VirGL/Venus on QEMU to provide "pieces"/"slices" of a GPU from the host to Guests/VMs. The problem with this is that using `dpdk`, this is running in user-space instead of kernel space, which is a...

I wanna create a VM for my new TrueNAS server and I decided to passthrough the onboard SATA controller to the VM. I have 4 SATA ports on the onboard SATA controller and I have a 2 port PCI SATA expansion card, which I have connected an SSD to, for installing Proxmox. The ids I'm using here are...

Hey Ho zusammen, ich habe ein Problem was ich einfach nicht gelöst bekomme. Das Problem: ich versuche einen Sata Controller (ASM1166) an eine VM durchzureichen. Erstmal ist es nur eine Basis Windows Server 2019 Datacenter Eval. Wenn ich die VM ohne die PCI Karte starte geht alles super. Füge...

Has anyone had success with passing through the Intel ARC A770M (or similar) to a VM (Windows or Linux)? I think I have vfio binding mostly working, however when I attempt to start the Windows 11 VM, it complains about VFIO being not ready/giving up on resets (causing the Proxmox task to...

I'm somewhat new to Proxmox but fairly skilled with Linux overall. I set up Proxmox on a retired mining machine build. I have researched and tried many, many things but cannot get the vendor-reset to work with the Radeon VII. Has anyone actually got this to work? The issue is this: VM will...

SOLVED BY SETTING CSM UEFI SETTINGS FOR THE PCIE LANES IF YOU ARE USING AN X79 CHINESE MOTHERBOARD WITH AMERICAN MEGATRENDS BIOS MAKE SURE TO TURN ON UEFI EXPOSURE FOR PCIE LANES IF YOU HAVE PVE INSTALLED WITH UEFI. YOU ALSO WILL NOT NEED TO USE A ROM FILE AS THE ROM BAR WILL BE FULLY EXPOSED...

I've spent the latter part of the last 24 hours trying to setup some VM's from backup onto PROXMOX 7.1-4. I was upgrading from an older version. Relevant hardware: Motherboard: Supermicro X10DRi-T (BIOS: 3.4a) CPU(s): Intel Xeon E5-2698v3 Hardware pass-through worked great until I performed a...

i am trying to hibernate a fedora VM to disk while a igpu is passed through. When hibernating the VM using qm agent 100 suspend-disk VM screen goes off and appears to start to hibernate, however it does not appear to complete and still shows as running within the Proxmox UI. when stopping the...

Hi, I'am new here, i hope you can help me/ give hint to be able to use a PCIe sound card inside a windows VM. Host machine: HP Proliant 380 Gen 9 CPU(s) 48 x Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz (2 Sockets) Kernel Version Linux 5.11.22-3-pve #1 SMP PVE 5.11.22-5 (Wed, 21 Jul 2021 18:25:44...

Hi!, I have some performance issues with Cyberpunk 2077 game, it has only 18-30 FPS / 10% cpu/gpu loading with GTX 1080 and 8 Ryzen 3700x cores, also Photoshop font transforms is very choppy, on bare metal everything work perfectly, any idea what the problem might be :rolleyes:? Configs...

Hi, i've camed in another thread to the Problem, that there is no easy way to bind vfio-pci to a bus device. This is neccessary if you can't do it with vendor:device id, because you have multiple devices and you need them on your host too. For example, if you want to passthrough one of four nic...

Hello together, TLDR: kvm segfault when starting VM with PCIe-GPU. I'm currently trying to pass through an GeForce GTX 1050 Ti via IOMMU using an E3-1240 V2 on a Supermicro X9-SCA F Board. Got iommu working, as far as I can tell from dmesg: [ 0.069454] DMAR: IOMMU enabled [ 0.133808]...
