Hi, I'm desperately trying to get a pass through pci device to a 11.2 kvm instance going on a openSUSE 11.1/i586 host, which is a VT-d capable machine: Xeon X3460, Asus P7F-E motherboard, Intel 3420 PCH chipset, 12 GB Ram, with the relevant options enabled in BIOS of course... According to: http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM I need to enable the IOMMU, but no matter, what I provide as kernel parameter to iommu (or do not provide iommu at all), iommu keeps out of sight: ~# dmesg | grep -e DMAR -e IOMMU ACPI: DMAR BF78E0C0, 0090 (r1 AMI OEMDMAR 1 MSFT 97) Tentatively running a 11.2 x86_64 installation has it: ~# grep -e DMAR -e IOMMU /boot-11.2-x86_64.msg <4>[ 0.000000] ACPI: DMAR 00000000bf78e0c0 00090 (v01 AMI OEMDMAR 00000001 MSFT 00000097) <6>[ 0.046487] DMAR:Host address width 36 <6>[ 0.046491] DMAR:DRHD base: 0x000000fed90000 flags: 0x1 <6>[ 0.046499] IOMMU fed90000: ver 1:0 cap c90780106f0462 ecap f020e3 <6>[ 0.046502] DMAR:RMRR base: 0x000000000e4000 end: 0x000000000e7fff <6>[ 0.046506] DMAR:RMRR base: 0x000000bf7ec000 end: 0x000000bf7fffff Probably, the 11.1/x86_64 kernel has it, too. Do I have a chance to get this going with 11.1/i586 (e.g. with only a modified kernel)? Or is it possible to run an x86_64 kernel with a i586 userspace? Unfortunately, for some reason I have to avoid upgrading this system to 11.2 or x86_64 by all means.
