I've been trying to setup a windows VM to use as a gaming desktop.

every time the installation finishes successfully, with the video card, keyboard and mouse passed through and working - and then i update the device drivers.

However, after i install the video card drivers the VM will bluescreen (either during installation, or after the reboot) and won't come back up.

 

This issue occurs using either seabios or OVMF, and in all versions of desktop windows from 7 to 10.

 

I'm only using the VM gui to configure the VMs, and did not edit any XMLs - is this what i'm doing wrong?

 

My hardware config is available here: https://pcpartpicker.com/user/Evilspice/saved/XG2v6h

 

oh, my video card is a Sapphire Radeon R9 285, but i experienced the same issues using an older nVidia card.

 

Help me, unraid-wan kenobi! you are my only hope!

 

Edit: forgot to mention, i'm using unraid version 6.1.9

come on people, can no one give me a hint? what should i do?

i doubt it's a problem with my video card, because i was able to install a steamOS VM yesterday.

 

could someone point me in the right direction?

 

thanks.

Ok taking a quick look at your iommu group your card is grouped in as below in group 1

 

1/devices/0000:00:01.0
1/devices/0000:00:01.1
1/devices/0000:02:00.0
1/devices/0000:02:00.1

 

02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Tonga PRO [Radeon R9 285]
02:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Device aad8

 

because there are other devices in the group with your card passthrough will not work properly.

 

What you need to try is to enable PCIe ACS Override: in the settings under vm manager. Then check if it is in its own iommu group.

 

You must get it in its own group else you will have problems. You can also try putting in different PCIe slots and check aswell.

Thanks, Gridrunner!

i enabled that and indeed the graphics card is now in it's own iommu group.

 

didn't have any luck yet with my win 10 VMs (one seabios, the other OVMF). i'll try with fresh ones during the weekend.

 

i'll update this thread with my progress.

Also you can try specifying the gpu rom file in the xml.

check this link http://lime-technology.com/wiki/index.php/UnRAID_6/VM_Management#Edit_XML_for_VM_to_supply_GPU_ROM_manually

 

You should find rom for your card here.
