Ide beirtam az iommu=1 opciot is, de ugyanugy ezt mondta:

Probalkoztam ezzel is (a dom0-ban):
# echo 0000:03:00.0 > /sys/bus/pci/drivers/pciback/permissive
De ennek hatasara sem mukodik a halokartya a domU-ban (ami
szinten Debian Squeeze). Termeszetesen az echo parancs utan
inditottam a domU-t.
Ez sem igazan biztato:

Letehetek arrol, hogy ez mukodni fog?
