1. How much NIC are bound to DPDK, show with dpdk-devbind --st. Is the DPDK NIC number match /etc/dpvs.conf ?
2. is the NIC supported by DPDK ? http://dpdk.org/doc/nics
3. Pls check README.md or doc/tutialor.md for examples.

The return value -5 means DPDK NIC is not enough according to config file. It's possible the NIC is not supported by DPDK. Pls check the return value of rte_eth_dev_count in check_lcore_conf.
You can also run DPDK examples like l2fwd first to see if NIC works with DPDK.

my server's CPU core number is 8, and i find there are cpu0--cpu8 in /etc/dpvs.conf, so i Commented-Out cpu8 , it's this part:

<init> worker   cpu8 {
    type        slave
   cpu_id      8
   port        dpdk0 {
        rx_queue_ids     7
        tx_queue_ids     7
        ! isol_rx_cpu_ids  16
        ! isol_rxq_ring_sz 1048576
    }
}

and then it works
