Guest's dmesg shows "Failed to initialize MSI-X interrupts." If not pinned an address with "addr=0x05", the VF will be pinned to ":00:03.0" by default, and that doesn't work. Normal vtd NIC assignment doesn't have this issue. commit:fda19064e of qemu-kvm.git is good. commit:44755ea36 of qemu-kvm.git is bad with this issue. There maybe something wrong between the two commit.
