Beginner Question: GPU pass-through different virtual systems

[Skyer]

Dear Support, dear Users,
thanks in advance for any information provided by you!

As a novice to Proxmox a question has raised:

Expecting this setting : 4 x GPU NVIDIA 1080 Founders Edition, 1 x CPU 8 Cores, 128 GB RAM

I read over the past few days that GPU pass-through is only possible if host and container have the same OS Debian -> Debian.

But these threads where relatively old and now I have to ask you:
Is it possible to pass-through a GPU from the host running Proxmox to a e.g. Ubuntu 16.04 Xenial or for the future Ubuntu 18.04 ?

Thanks in advance for our answers!!
Yours sincerely
Skyer

do you talk about passthrough to containers (which i have no experience with), or to virtual machines (with qemu)

if it is the latter (qemu), then this:

I read over the past few days that GPU pass-through is only possible if host and container have the same OS Debian -> Debian.

is not true (i have a proxmox host with a windows 10 vm with a passed through gpu)

the only tricky thing is hardware support, the mainboard has to support proper iommu grouping, and the cards can also either work or not (there have been some thread on the subject already)

if you talk about containers, i honestly have no idea how to do that and the requirements of it

Hi dcsapak,
yeah you could be right, I do not have any experience by using Proxmox with a windows vm.

My question is aimed on be using proxmox on linux and I want to create a container with ubuntu. And the Ubuntu container should use one of four GPUs of the host system.

Best regards
