you should verify that iommu grouping is correct and works, e.g. with 
this script (courtesy of the arch linux wiki)

----8<-----
#!/bin/bash
shopt -s nullglob
for d in /sys/kernel/iommu_groups/*/devices/*; do
     n=${d#*/iommu_groups/*}; n=${n%%/*}
     printf 'IOMMU Group %s ' "$n"
     lspci -nns "${d##*/}"
done;
---->8-----

also verify that vt-d is activated in the bios
