Hi all, I would like to get my system to work with IOMMU. (The long-term goal is VGA passthru.) System is as follows: CPU: Core 2 Duo E6600 MB: Foxconn G9657MA-8EKRS2H (w. latest bios: 631F1P61) Virtualization support is enabled in BIOS. (These is only one option.) Hypervisor: xen 4.0.0 from Debian, AMD64 Xen config: iommu=verbose output of xen dmesg is attached. HVM domains work (lasd tried with xen 3.2), but IOMMU is disabled, according to xen dmesg. What can I do to increase the chances of getting this to work? Thank you for your help: Kristof Csillag _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

This is not a software feature, but a chipset on the board. Look at this list: http://en.wikipedia.org/wiki/List_of_Intel_chipsets and look for VT-d. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
