problem with configuration gpu passthrough

[Arslan97]

hi guys, i have a problem with my server...
i have proxmox installed and a vm debian i'm trying to do the passhtrough of the gpu but it still not working.
when i start the vm gives me this "kvm: -device vfio-pci,host=0000:04:00.1,id=hostpci0.1,bus=ich9-pcie-port-1,addr=0x0.1: vfio 0000:04:00.1: failed to setup container for group 13: Failed to set iommu for container: Operation not permitted"
anyone can help me ??
the gpu is a 1060.

04:00.1 is probably the audio function of the GPU. Are you passing the VGA and audio functions separately with All Functions enabled, perhaps? Please show the VM configuration (file from /etc/pve/qemu-server/ or qm config VM_ID_NUMBER).

You might have a RMRR problem (check with journalctl). Are you using a HP server? I have no experience with that issue but you might want search the forum for possible solutions.
