I know I had to use ovmf to get my 1050ti working. I would suggest trying that again, especially since you're using a modern graphics card. I would also try dropping driver=vfio, and maybe pcie=1 as well.

Can you run the command I put in my first post? # dmesg | grep -e vfio I want to make sure vfio is grabbing your video card's device IDs. Have you specified ovmf in your vmid.conf file, bios: ovmf or are you using one of the SeaBios methods from here...

What do you see if you run: # dmesg | grep -e vfio You might also need to passthrough your video card as a multifunction device, since it has an HDMI audio chip onboard. In your VMID.conf file, change: machine: q35 hostpci0: 0b:00.0,pcie=1,x-vga=on to: machine: q35 hostpci0...

I've been experimenting with PCI/PCIe passthrough this week, and actually managed to get it working. However, the fly in the ointment has been audio. USB audio was horribly garbled. Passing through the host's onboard audio works a lot better, but I still get crackling and skips in the audio when...

Most guides out there presume that you have a UEFI system that you want to use GPU passthrough. There's some discussion of BIOS GPUs, but not much discussion of what to do if you have an older PC and a newer UEFI video card. Looking on this page ( https://pve.proxmox.com/wiki/Pci_passthrough )...

I've been using Proxmox as a virtual lab to study Windows Server installation and configuration. One feature I'd like to learn and use is Hyper-V. Hyper-V does not support some features that I want, so I'm not looking to install it long term. However, unless I can figure out how to nest it in...

Thanks, worked perfectly.

"dkms status" reports: nvidia-current, 340.96, 3.16.0-4-amd64, x86_64: installed nvidia-current, 340.96, 4.2.8-1-pve, x86_64: installed If it matters, I have an MSI GTX 670 2GB. I can try to install the kernel modules from the Nvidia website, but I'd rather stick with the Debian repos, if...

Please note that I'm not trying to install NVidia drivers in a guest OS, but rather the HOST OS. Somehow I got them working with kernel 4.2.8, but since upgrading to kernel 4.4/Proxmox 4.2 I've been unable to duplicate my previous success. I have a full install of Debian Jessie 8 with the...

Why did you skip adding in an entry in hosts? It's there for a reason. There is no interactive install when you install on top of Debian Jessie, which may explain why vmbr0 was not created automatically. Look here for help setting up networking in Debian...

Well, I just answered my own question. I installed Proxmox on both systems, then tried to install Windows Server into a VM. Even though I assigned two cores to the VM on the quad, and had the benefit of an SSD, WIndows installed about twice as fast on the tri-core Athlon. Really an eye opener...

I'm trying to create a low-budget lab for learning about server operating systems and virtual environments. I'm having to choose between two different systems I have available. One is a Core 2 Quad running at 2.2 Ghz, but without SLAT. The other is a triple core Athlon II X3 at 2.9GHz. Though it...

Thanks so much, the apt-get command worked perfectly. I now have graphics acceleration with kernel 4.2. Am I reading your comments correctly that DKMS should now be automatically recompiled every time there is a PVE kernel update? Or do I need to do this manually the next time Proxmox pushes out...

Actually, I didn't compile anything. I used the fglrx driver/module from the Debian non-free repository, installed thusly: # apt-get install fglrx-driver In a situation like this, I would normally prefer to use the open source driver. However, according to this: https://wiki.debian.org/AtiHowTo...

OK, if I go to the advanced GRUB menu and boot with kernel 3.16 I get accelerated graphics. Is this expected behavior? Can I change the default kernel back to 3.16? What do I lose by reverting to an older kernel?

Fresh install of Debian Jessie (see here: http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Jessie ) with a Radeon HD 5750 as the GPU. Apparently development of the open source driver for this old graphics card has been abandoned, however there is a legacy proprietary driver (fglrx) still...

I've been trying to use VirtualBox on my laptop as a sort of mobile lab, to get some hands-on experience with server OS's. However, the laptop only has 8GB of RAM, and I found myself only able to run 2 VMs at a time. If I tried 3 or 4, I'd start hitting my swap partition. So a friend suggested...

Thanks, Udo, worked like a charm. I wonder how "myhostname" got into nsswitch.conf. It's a new, vanilla install of Debian 8. Thanks again.

I'm trying to set up Proxmox with Debian 8 on a laptop to create a mobile lab running a few Windows servers. I went ahead and tried to set it up on Debian 8 with these instructions: EDIT: Can't post links. Google "install proxmox on debian jessie" to get the link. However, I’ve hit a...
