Hi Weidong, I'm wondering what tree you are using for SR-IOV dom0 development. Also, I am guessing its not linux-xen-2.6.18.8, but are you aware of the status of SR-IOV in that tree? In particular, the igb driver seems to not have SR-IOV support. I am considering back-porting it, but I'd like to avoid duplicating the efforts of others.
