dundundundudun Posted August 21, 2015 Share Posted August 21, 2015 Domain id=4 is tainted: high-privileges Domain id=4 is tainted: host-cpu char device redirected to /dev/pts/0 (label charserial0) is the only thing that shows up in the VM log. im using the following: Asus P8Z68 DELUXE & i5 3570S (Motherboard doesn't have on-board video) MSI 8500GT Sapphire 7870 XT Clicking Info in the webui shows HVM: Enabled IOMMU: Enabled i've tried passing through both those cards and it gives me the same thing, i've been trying to look for a solution but i have no idea whats going on or how to fix it, any help seriously appreciated.

FLK Posted August 21, 2015 Share Posted August 21, 2015 Did you try with both plugged in at the same time ? I' not sure wether you can pass through with only one GPU. (At least with an iGP that doesn't work) Link to comment
jonp Posted August 22, 2015 Share Posted August 22, 2015 What steps have you tried from the wiki? http://lime-technology.com/wiki/index.php/UnRAID_Manual_6#Assigning_Graphics_Devices_to_Virtual_Machines_.28GPU_Pass_Through.29 Link to comment

(At least with an iGP that doesn't work) yes i've tried with both plugged in. What steps have you tried from the wiki? http://lime-technology.com/wiki/index.php/UnRAID_Manual_6#Assigning_Graphics_Devices_to_Virtual_Machines_.28GPU_Pass_Through.29 Changing BIOS to SeaBios and OVMF Changing Machine Type Tried PCIe ACS Override Set ON Tried supplying the GPU ROM manually through the XML i can set the CPU to emulated and Domain id=4 is tainted: host-cpu stops showing but it will still give me Domain id=4 is tainted: high-privileges. I set the GPU to VNC and it boots the VM fine (with the CPU Passthrough) really no idea..... Link to comment
jonp Posted August 22, 2015 Share Posted August 22, 2015 In your BIOS, look for a setting related to graphics. If their is an option to choose on board vs pcie, choose on board. Try that and report back. Link to comment

Try that and report back. I've tried the different settings in BIOS but it hasn't done anything, im starting to think it might be the motherboard. Link to comment
jonp Posted August 23, 2015 Share Posted August 23, 2015 Just an FYI, the messages in the VM log are absolutely fine. They happen when GPU assignment works or not. They are not error messages at all, in fact, but rather, just letting you know that you can't use VM live migration features, which is fine, because we don't support that anyway (enterprise / business class feature). All of that said, I'm not 100% sure it's your motherboard. It could be those particular GPUs. Hard to tell without being able to test them on another IOMMU capable motherboard. Link to comment

I do have another board i could try but im not entirely sure if its IOMMU capable and it means taking it apart and swapping out CPU not that big of a deal though. could you recommend another GPU that's known to work? NVIDIA or AMD something on par with the 7870 i have. Link to comment
dundundundudun Posted August 24, 2015 Author Share Posted August 24, 2015 What's your budget? $200-$400 This puts me in range of the 970 GTX but ideally i'd like to spend less then $400. Link to comment
dundundundudun Posted August 24, 2015 Author Share Posted August 24, 2015 Evga 970 works fantastic. I'll have to wait until Thursday if i want to get it, in the mean time I'll test out the other board tomorrow and see if it makes a difference. Link to comment
jonp Posted August 24, 2015 Share Posted August 24, 2015 Ok, no prob. Folks have gone even cheaper than that like the GTX 750, but it all comes down to $$$ vs horsepower. Link to comment
mostlydave Posted August 24, 2015 Share Posted August 24, 2015 My board does not have onboard video, and would not pass through the GPU I wanted (GTX 750) until I also installed an older GPU and did not pass it through. That may be an easier fix or test for you than swapping out boards Link to comment

That may be an easier fix or test for you than swapping out boards In the OP he shows having two GPUs already and tried passing through either results in the same. He has left both attached I believe. Link to comment
dundundundudun Posted August 24, 2015 Author Share Posted August 24, 2015 I swapped CPU's and tried the other motherboard. Checked to see if it supported IOMMU in the unraid webui this is what i got: HVM: Enabled IOMMU: Enabled Went into the bios of the MB was able to choose between igpu, pci, pcie for primary display i chose igpu there was also another option that would empower both igpu and pci/pcie (multi monitor) i tried the vm with it enabled and disabled. results: same issue as OP.

jonp Posted August 25, 2015 Share Posted August 25, 2015 Ok, did you check for a motherboard BIOS update? Link to comment
dundundundudun Posted August 25, 2015 Author Share Posted August 25, 2015 Ok, did you check for a motherboard BIOS update? both motherboards already have the latest bios updates. i'm going to be borrowing a different gpu (550 gtx) from a friend and see if that does anything at least when he decided to let me use it.

jonp Posted August 25, 2015 Share Posted August 25, 2015 The GTX 550 can be problematic, but it should at least light up your monitor. How old are the GPUs / motherboards / processors you have tested with? I'm pretty shocked that you're having so much difficulty. If they are several years old, that could be the issue (just poor IOMMU implementation or odd GPUs). Link to comment

Ivy Bridge LGA 1155 so not the current Haswell tech. i5 3570S - pretty much new Sapphire 7870 XT -had this for 3+ years Motherboards i havent had long < year. im thinking it might just be the motherboards and shitty IOMMU support from shitty Asus. i may just sell everything i have and buy current with tested hardware for now i'll wait until i can get the 550GTX to test some more. If i decide to buy new hardware what should i be looking at in the mid range? I need VM and GPU Passthrough capabilites Link to comment

I just need 1 gpu for a single VM, maybe a sound card but im not sure how much of a benefit passing a sound card to a vm is going to give me. Link to comment

Do you want to go new CPU as well (haswell series) or do you want to try to stick with the CPU you have already? If you stick with what you got, it might work just fine with another motherboard. If you go completely new CPU/Mobo, I would push you to purchase based on a system I have tested and working (http://lime-technology.com/wiki/index.php/UnRAID_Manual_6#Workstation_.283_of_3.29). That system has 10 SATA ports on the mobo itself and I've tested it with several GPUs now and it works really solid. Link to comment
