With VT-d Posted-Interrupts enabled, external interrupts from direct-assigned devices can be delivered to guests without VMM intervention when guest is running in non-root mode. You can find the VT-d Posted-Interrtups Spec. in the following URL: http://www.intel.com/content/www/us/en/intelligent-systems/intel-technology/vt-directed-io-spec.html This series was part of http://thread.gmane.org/gmane.linux.kernel.iommu/7708.
