 Am I still able to use gfx_passthru if I get this messages from xm dmesg?:
    ...
    (XEN) Intel VT-d Snoop Control not enabled.
    (XEN) Intel VT-d Dom0 DMA Passthrough not enabled.
    (XEN) Intel VT-d Queued Invalidation not enabled.
    (XEN) Intel VT-d Interrupt Remapping not enabled.
    (XEN) [VT-D]iommu.c:847: iommu_fault_status: Fault Overflow
    (XEN) [VT-D]iommu.c:850: iommu_fault_status: Primary Pending Fault
    (XEN) [VT-D]iommu.c:825: DMAR:[DMA Write] Request device [00:02.0] fault
addr ffffff000, iommu reg = fff16000
    ...
    (XEN) Enabling APIC mode:  Flat.  Using 1 I/O APICs
    (XEN) I/O virtualisation enabled
    ...

I can see I/O enabled but all the VT-d features are disabled, so maybe
that's why with the last revision of XEN I can't have I/O virtualisation
enabled, anyone have an answer?

Thanks in advance
