It is based on a gentoo system with kernel 3.7.10 and qemu 1.2.2-r3 from the gentoo portage. I tried to assign a PCIe card to a guest system. I followed the manual on http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM And after I rebooted the system it says: dmesg | grep -e DMAR -e IOMMU [ 0.000000] Intel-IOMMU: enabled [ 0.000000] Intel-IOMMU: disable GFX device mapping But I cannot see similar lines like on the page. Could it be, that my mainboard and/or CPU does not support IOMMU? Could it help to replace the CPU? The current system is a ivy bridge system.
