I think i might have solve it. For some reason grub2-mkconfig doesnt work. (Have no idea why) I manage to solve it with grubby. sudo grubby --args="intel_iommu=on" --update-kernel=ALL For some reason it works. I dont know if it works if my kernel gets upgraded. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
