I need to retest my set up with multi-threads vhost. My previous set up
applies to single thread vhost. The single stream netperf/netserver set
up, for example, if we have two quad-cores sockets to get the consistent
9.4Gb/s BW:

socket 1:
cpu0: netperf/netserver
cpu1: ixgbe 10GbE NIC IRQ
cpu2: I/O thread
cpu3: vhost thread

socket 2:
cpu0: QEMU VCPU0
cpu1: QEMU VCPU1
