Hi,

 

I am planning to deploy 2 VM on my unraid. Each VM will have dedicated GPU assigned.

 

Is there any requirement for this setup? Can I used same GPU model on my unraid?

 

My current setup are as below:

Motherboard: GIGABYTE Z490 VISION G

Processor: CORE I9 10900K

RAM: VENGEANCE LPX CMK (3600) 16GB x 2

Hi

 

Yes you can. I have a PC with 2 GPU's (RTX 2080 Super and an old GTX1080 Super) that works fine.

my latest project is a PC with 5 GPUs (4x RTX 2060 and a GT710) that also works very well, except that my new Threadripper does not release the GPU in the 1st slot for GPU Passtrogh. But i'm working on it....

Thank you for sharing your experience. I'll looking forward to include multi GPU in my build.

Is GPU passthrough working now on 6.9.2 ? didnt seem to be the case a month ago at least, alot of people had to revert to 6.8.3. I would like to know your experience.

I am on 6.9.2 and can passthrough gpu(s). 

Asus rogstrix 470 MB, Ryzen 3900x.

I have the same setup as you with gtx970 on the 16x slot and I cannot get mine to work.  It used to work but unraid updated and it stopped working. It has almost been a year and I would like to get this resolved.  I also have an sas card in the bottom slot. 

Would you mind sharing your configuration or bios settings?  I believe unraid is set to non uefi (legacy) mode if that matters.

I'm on this bios: American Megatrends Inc. Version 5843. Dated: 03/11/2021

 

and have the following:

• 1st slot Radeon RX 570 which I use for MacOs and Windows VMs
• 2nd slot GeForce GTX 1650 for Archlinux Vm - daily driver
• 3rd slot GeForce GTX 1050 Ti - hardware acceleration. i.e plex, zoneminder, mlapi, etc.

 

I'm on Legacy boot. non uefi. In bios I've only modified the following:

 

• HVM: Enabled
• IOMMU: Enabled
• Memory Freq: 3000
• Power state: Power on restart
• Fans: all at max

 

I think that if you're passing the only GPU you have, you need to add the GPU bios in the vm.

Thank you very much.  I am using the edited rom file.

Did you edit the vifo on the unraid bootup process or just change settings on the VM screen?

 

I only added the vbios on the VM set up tab. 

And you'll also need to bind that card in tools >> device setting.

Well, I got it to work once; it booted to uefi bios and then the vm worked.  I then needed to reboot my vm and it never came back up so using my phone I logged into the unraid machine and the vm would restart but nothing on the monitor anymore. Rebooted unraid and nothing.

So If I passthrough like your saying to by assigning the immo graphics card/hdmi sound then unraid will not grab the card on boot.  I assume you have your vm to auto boot?

 

I will try this and report back.

 

What I am trying to do is have 2 gpus for passthru to 2 seperate vms

 

Problem: Installed 2nd gpu in unraid server (identical amd rx570 8gb cards)

when I start a single vm....my vms tab disappears and go to settings vm manger and thats gone too

 

Setup: I have a linux vm and a windows 11 vm installed

when it comes to vm setup each vm has its own gpu with seperate id (so I know which card is
which), each card has its own iommu group

 

Outcome: My server becomes so unstable to the point I have to reboot, because it freezes so I cant get any logs to see whats wrong........

at first I thought it was a power issue, I started with a 750w psu running 2950x threadripper 6 hdds and 2 amd rx570 8g gpus

 

So I upgraded the psu to a 1000w psu and getting same issues, So I have taken out 2nd gpu and system is now stable once more......

Im not sure if its a setup thing or that I have identical gpus

 

If someone has some insight to dual gpu setup that would be great, Im not sure what to check for in logs.........any help would be greatful, a bit lost and disappointed I cant get this working

 

I have same results with 6.9.2 and now with 6.10 rc1

what case /chassis are you using for this? i have a similer project with 4-5 cards and threadripper and am struggling to find a suitable case/chassis for it

What about the fractal design 7 xl?

I have an old fractal design xl r2 and it was near perfect.

The new 7 xl is quite expensive (at least for me), but it seems it has all one should have need; it has also a 3 vertical slot space to install a pcie riser.
