with a amd gpu can you run windows or ubuntu under unraid without needing 2 gpue

[adiack]

i am running unraid on my server 

it has a ryzen 7 2700

32 gb of ram

and a rx 480 gpu

can i run windows or ubuntu server or any Linux server that supports steam  under unraid without adding anuther gpu

You can passthrough an AMD card to a VM on UnRaid (QEMU), but no idea if you can do it if its your only GPU. 

Why not try?

like a nvidia tesla

AMDs equivalent to NVIDIAs vGPU is called SR-IOV. There was talk a long time ago about AMD planning to enable this feature on their desktop cards but it never came to fruition.

 

It's possible that you can if you can detach the GPU from the Kernel at startup. You can detach it in one of 3 different ways.

1. Blacklist the driver
2. By Device ID
3. By Device Address.

The problem is without another GPU or iGPU you won't have any access to the GUI or Terminal if something goes wrong. Make sure you install OpenSSH-Server.

you always need a GPU for the host OS to grab, so yes you can passtrough the gpu, but no, it cant be the only gpu in your system.

Check if your motherboard has some built-in GPU. That might be of help. Otherwise, you will definitely need a second one. Another option would be using free ESXi as a hypervisor and running Unraid on top as a virtual machine. This approach requires some numerous efforts on rebuilding all the stuff but might work on a single GPU. Since VMware has made some numerous improvements on GPU pass-through performance https://www.vmwareblog.org/vmware-covered-performance-gap-physical-virtual-gpus/ I would give this a try.

Is this from experience with AMD GPU's these statements? 

I have a single Nvidia GPU in my UnRAID box being passed to an Ubuntu VM then being passed to Docker, and it works just fine by unbinding it.

Yes. It worked for me with an RX460 and Ryzen that has a graphics chip inside. But didn't with just the external AMD GPU. I don't exclude my "crooked" hands here being an NVIDIA fanboy anyways.

does your unraid box have a cpu with igpu?

No, as I said its a single GPU. Theres no iGPU.

I never understand people saying the host os needs a gpu. I’ve always passed through all gpu’s to vm’s. Works just fine. Just run unraid without a gui and with a network connection. Enter the ip you see after booting in a browser and do ur unraid things. Start a vm and it will just bind the gpu. Screen on it will go black for a second and then just show the bootscreen of whatever os is on the vm.

rebooting might be an issue with some amd gpus and all nvidia gpus though. As it rebinds it when rebooting the vm. Some gpus dont like that. Never been able to do it with an nvidia gpu. If it does it once it does it always. Do just try it. If it doesnt work just use the browser on another pc to reboot unraid.

How do you turn of the gui

You dont "turn it off", you just dont use the local GUI, you manage it completely remotely through your browser and putty.

during the boot of the PC you get a menu, select the one without a GUI. Then you'll get a CLI.
