It seems you lack scope descriptions for the PCI devices in the system.
At least, this is what our jailhouse config generator complains about
right now (didn't look into details yet). If so, the guest OS will
likely not configure the IOMMU appropriately as it thinks that the
devices are passed through anyway.
On Intel, there is an easy way to state "catch them all" in the ACPI
table. Maybe AMD has this as well so that you don't need to add
individual devices.
