Unraid error with PCI passtrough

Hi,

 

I'm new to the whole Virtualization through GPU. I want to try a cheap 2 player gamer pc.

I bought a server board dseb-dg/sas from asus with 2 pci express slots and 2 771 cpu slots with 2 xeon x5450 quad core processors.

 

I followed every step from linus on YouTube

 

 

And i get this error:

 

internal error: qemu unexpectedly closed the monitor: 2017-05-15T12:20:42.511301Z qemu-system-x86_64: -device vfio-pci,host=0a:00.0,id=hostdev0,bus=pci.0,addr=0x5: vfio: failed to set iommu for container: Operation not permitted

Group 2 is the group for my GPU

if i go through VNC i can start up de virtualisation but through my GPU it gives this error.

vt-d is enabled in the bios the only thing i don't know is if the xeon 5450 support vt-d. can't find anything about that

 

my sytem information:

Model: Custom

.

 

also, is there maybe a free software for virtualisation with GPU?

 

thank you in advance!

 

greetings,

virtualization rookie

Post your IOMMU groups. (Tools> system devices). Sounds like you have more than one device in IOMMU group 2.

if thats the case, you'll need to enable the PCIe ACS Override patch in Settings>VM Manager (enable advanced settings, reboot after changing) to break up the IOMMU groups so you can pass that device through.
