    Iam at the same point. Today got my Asus Crosshair IV and I can confirm all the settings/outputs.
    Just installing Ubuntu with xen, will try KVM too.

    Is that correct? Does iommu=1 need to be set in the kernel args? Is it set?

    Otherwise it looks really promising! I now really hope that the other motherboard manufacures tell their BIOS vendor/team to write in support for this feature. Otherwise, I'll dump my Gigabyte board for the ASUS board. It seems everything works on that board? Thanks again!

    By default it is disabled for paravirtualized guests, see XenPCIpassthrough - Xen Wiki

    Yes, you can use the more safe and secure hardware IOMMU (VT-d) passthru also for PV guests, instead of the normal Xen PV PCI passthru. As a default Xen uses the normal (non-IOMMU) PV passthru for PV guests.
    You need to add "iommu=pv" boot option for Xen hypervisor (xen.gz) in grub.conf and reboot. After rebooting verify from "xm dmesg" that IO virtualization for PV guests gets enabled. Naturally you must have hardware IOMMU (Intel VT-d or AMD-V) support for this to work.

    Ah, OK. I didn' know that. Thanks jdma.

    On another note, I just submitted a technical support ticket to Gigabyte, like I said I was going todo a few pages back. Hopefully we shall hear from them shortly.
    My question was:

    Will Gigabyte be supporting IOMMU (I/O Memory Management Unit) or also called AMD-Vi in the BIOS just like the ASUS Crosshair IV and MSI motherboards with the 890FX chipset? Thank you for your time.
    Short, sweet and to the point... unlike my other question. Fingers crossed!

    According to the respective PDF manuals MSI and Asus both use the AMI v2.61 BIOS while Gigabyte has an AWARD v6.00PG BIOS. Now hopefully it won't take AWARD too long to assist Gigabyte in developing an IOMMU 1.2 implementation but you'll never know...

    Oh-well, getting over excited for nothing. I reflashed anyway in hopes that it was an undocumented feature... no IOMMU/AMD-Vi support in this latest revision, F3.

    Back to waiting! ...

    Thanks stasio for letting us know.
