I'm using qemu 2.7.0 with kernel 4.8.8 and met the following issue on an Intel 
board. But qemu 2.4.0 works well with kernel 4.8.8 with the same parameter on 
the same board."04:00.3" is the NIC device id.It seems the interrupt type is 
not recognized.

Anyone met the same problem? What might cause this? Thank you.
