KVM reports that I
do not have an IOMMU, however, dmesg reports both DMAR and IOMMU.  In

Does your kernel .config actually include iommu support?


Is it a config other than any of these?  Which one supports VT-d?


root@ubuntu:/boot# grep IOMMU config-2.6.35-6-server
CONFIG_GART_IOMMU=y
CONFIG_CALGARY_IOMMU=y
CONFIG_CALGARY_IOMMU_ENABLED_BY_DEFAULT=y
CONFIG_AMD_IOMMU=y
CONFIG_AMD_IOMMU_STATS=y
CONFIG_IOMMU_HELPER=y
CONFIG_IOMMU_API=y
# CONFIG_IOMMU_DEBUG is not set
# CONFIG_IOMMU_STRESS is not set

CONFIG_DMAR.
