Proxmox 5.3 - Tesla P40 vGPU issues

Hey dominiaz,

do you actually working with the nvidia vgpus on proxmox? and is it still working stable?

the cards are made for rendering / machine learning / video trancoding and so on but not for gaming. do you think it's possible to use this card in a vm for "gamestreaming VM"
 
Card works very very stable on Proxmox 5.4.

I have some issues on 6.x.

I think that gamestreaming VM will be working very good.

Why didn`t you passtrough "normal" gamer card to VM?
 
Hello!
Do you want to say that I can take Tesla T4 and give my Windows virtual machines a vgpu profile (for example: 8 virtual machines with 2 GB of video memory?) ???

And I just need to buy nvidia licenses for the Nvidia vDWS?

Yes, exactly.
Just install proxmox 5.4 because its the most stable version for vgpu.

Can you share some details howto start with Tesla T4. There is a lot of demand for vgpu support for proxmox and no real good guide oder documentation howto start
  • Do I still need to buy Grid Licences?
  • What software needs to be installed on proxmox hosts or does it work out of the box?
  • Are there special drivers that need to be used?
  • How can I provide a vm a vgpu?
  • What problems occure on Proxmox 6.x?
Sorry for the many questions. We are thinking about buying a Tesla T4, but want to collect as many information before buying.
Thank you very much, would really appreciate some details how you managed it.

Edit: I see there is a little information in this thread how you managed it, is this still correct? Anything that should be mentioned for someone who wants to get startet with Nvidia Tesla T4?

Instruction step-by-step:

1) Enable iommu on proxmox host: https://pve.proxmox.com/wiki/Pci_passthrough
2) Download NVIDIA vGPU for Linux KVM (NVIDIA-Linux-x86_64-430.67-vgpu-kvm.run or newer) from https://nvid.nvidia.com/dashboard/
3) Execute code on proxmox host
Code: 
chmod +x NVIDIA-Linux-x86_64-430.67-vgpu-kvm.run
apt install gcc make pve-headers-`uname -r`
./NVIDIA-Linux-x86_64-430.67-vgpu-kvm.run
mkdir /usr/lib64
ln -s /usr/lib/x86_64-linux-gnu/libnvidia-ml.so /usr/lib64/libnvidia-ml.so
ln -s /usr/lib/x86_64-linux-gnu/libnvidia-vgxcfg.so /usr/lib64/libnvidia-vgxcfg.so
ln -s /usr/lib/x86_64-linux-gnu/libnvidia-vgpu.so /usr/lib64/libnvidia-vgpu.so
ln -s /usr/lib/x86_64-linux-gnu/libnvidia-cfg.so /usr/lib64/libnvidia-cfg.so
4) Reboot proxmox host
5) Add it all vm with diffrent uuid 'args: -uuid 00000000-0000-0000-0000-000000000100' to vm file /etc/pve/local/qemu-server/100.conf

Hey,
I'm running into the same issue, but im using the nvidia-vgpu-ubuntu-510_510.73.06_amd64.deb installer.

Error:

root@pve:~# qm start 100
swtpm_setup: Not overwriting existing state file.
kvm: -device vfio-pci,sysfsdev=/sys/bus/pci/devices/0000:01:00.4/00000000-0000-0000-0000-000000000100,id=hostpci0,bus=ich9-pcie-port-1,addr=0x0: warning: vfio 00000000-0000-0000-0000-000000000100: Could not enable error recovery for the device
kvm: -device ide-cd,bus=ide.0,unit=1,drive=drive-ide1,id=ide1,bootindex=103: Can't create IDE unit 1, bus supports only 1 units
stopping swtpm instance (pid 1720) due to QEMU startup error
start failed: QEMU exited with code 1

This fix didnt help 5) Add it all vm with diffrent uuid 'args: -uuid 00000000-0000-0000-0000-000000000100' to vm file /etc/pve/local/qemu-server/100.conf

anyone have another idea?
