VT-d Posted-Interrupts is an enhancement to CPU side Posted-Interrupt.
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.
This patch is used together with the patches in KVM side.
You can find the VT-d Posted-Interrtups Spec. in the following URL:
