Let Qemu set the flag is not that stright forward, it will impact the performance dramatically. In kernel irqchip will help u on this, but the foundmental stuff to support either VT-d or directly hardware pass thru is still under going. So you probably have to wait for this :-( BTW, is this hardware shared among different VMs or dedicate to each VM? > and ack the interrupt from the host side.
