GPU pass through problems

Hello everyone,

I am fairly new to unraid and virtualization. Currently, I have been having troubles with vms booting with a gt710. Whenever I start a vm this comes up.

internal error: qemu unexpectedly closed the monitor: 2020-01-10T05:35:14.681545Z qemu-system-x86_64: -device vfio-pci,host=04:00.0,id=hostdev0,bus=pci.0,addr=0x5,romfile=/mnt/disk1/domains/vbios/gt710.dump: vfio 0000:04:00.0: failed to setup container for group 13: failed to set iommu for container: Operation not permitted

 

Here is my system info

Model: Custom

M/B: Dell Inc. 0F0XJ6 Version A01 - s/n: ..CN7016304600BC.

BIOS: Dell Inc. Version 6.6.0. Dated: 05/22/2018

CPU: Intel® Xeon® CPU E5645 @ 2.40GHz

HVM: Enabled

IOMMU: Enabled

Cache: 192 KiB, 1536 KiB, 12288 KiB, 192 KiB, 1536 KiB, 12288 KiB

Memory: 32 GiB DDR3 Multi-bit ECC (max. installable capacity 192 GiB)

Network: bond0: fault-tolerance (active-backup), mtu 1500
 eth0: 1000 Mbps, full duplex, mtu 1500
 eth1: interface down
 eth2: interface down
 eth3: interface down

Kernel: Linux 4.19.56-Unraid x86_64

OpenSSL: 1.1.1c

 

Whenever I start it using vnc, it is fine.

 

I figured it out now.

For the other noobs out their like me, for you to run a vm with gpu passthrough, you need two gpus.
