Hi Feng, we are not applying new features to legacy KVM device assignment, since it is unsafe (it does not honor ACS). I and Alex can help you with designing a way to interface VFIO with KVM posted interrupts. Give us a few days to study these patches more, or feel free to request comments if you have ideas about it yourself. Paolo
