Also, I wasn't sure at first what you meant by "native VT-d" ... you mean DMA-API VT-d usage as opposed to KVM device assignment usage, right? Perhaps we need a better term for that distinction.
dma-api is request-oriented (the API is called to set up and tear down a single dma request), while the kvm usage is address space oriented (the API is called to set up, maintain, and tear down an address space, over which many dma requests can run). Perhaps someone can come up with names that reflect that.
