I see now there are a few exceptions to the Vt-d support, the wikipedia pages list those: http://en.wikipedia.org/wiki/List_of_Intel_Core_i5_microprocessors#Mobile_processors http://en.wikipedia.org/wiki/List_of_Intel_Core_i7_microprocessors#Mobile_processors You can check your laptop for compatibility like so: AMD Machine dmesg | grep AMD-Vi ... AMD-Vi: Enabling IOMMU at 0000:00:00.2 cap 0x40 AMD-Vi: Lazy IO/TLB flushing enabled AMD-Vi: Initialized for Passthrough Mode ... Intel Machine dmesg | grep -e DMAR -e IOMMU ... DMAR:DRHD base: 0x000000feb03000 flags: 0x0 IOMMU feb03000: ver 1:0 cap c9008020e30260 ecap 1000 ... From: http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM#VT-d_support You would need to pass iommu=1 on the kernel line if using Xen (I think). Something to try anyway.
