All,
PLease help. I have scoured the internet everywhere i can to find out how to get my controller on my Dell r 710 to pass through to my trueNAS VM. I replace the stock raid controller with one flashed to IT mode. I followed the wiki instructions and have enabled iommu in the GRUB file. I also verified the controller is isolated to iommu group 17. However, every time I boot the VM i get the following error.

kvm: -device vfio-pci,host=0000:05:00.0,id=hostpci0,bus=pci.0,addr=0x10: vfio 0000:05:00.0: failed to setup container for group 17: Failed to set iommu for container: Operation not permitted
TASK ERROR: start failed: QEMU exited with code 1

i do see that ios has interupt remapping enabled but it gets disabled. I used the script in the wiki to allow unsafe interrupts.

I would greatly appreciate any help you all could provide. I am new to Proxmox and Linux.
