To enable PCI passthrough, you need to configure:
INTEL
edit:
#vi /etc/default/grub
change
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"
then
# update-grub
# reboot
Then run "dmesg | grep -e DMAR -e IOMMU" from the command line. If there is no output, then something is wrong.
AMD
Edit:
# vi /etc/default/grub
Change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
To:
GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on"
Then:
# update-grub
# echo "options kvm allow_unsafe_assigned_interrupts=1" > /etc/modprobe.d/kvm_iommu_map_guest.conf
# reboot
