[na zhu]

Dear experts,

I try to use dpdk ovs to improve the NFV performance. I follow all the
instructions of INSTALL.DPDK.md, when i do dpdk vhost vm configuration with
libvirt, the vm can not created. the error is:
root@juno:~/vm# virsh define dpdk0.xml
Domain dpdk0 defined from dpdk0.xml

root@juno:~/vm#
root@juno:~/vm# virsh start dpdk0
error: Failed to start domain dpdk0
error: internal error: process exited while connecting to monitor: **

My dpdk0.xml file is:

I create a ovs bridge:
root@juno:~/vm# ovs-vsctl show
199fdc65-a790-4edc-bf4a-baf8dedf2d32
    Bridge "br0"
        Port "dpdk0"
            Interface "dpdk0"
                type: dpdk
        Port "dpdkvhost0"
            Interface "dpdkvhost0"
                type: dpdkvhost
        Port "br0"
            Interface "br0"
                type: internal
        Port "dpdk1"
            Interface "dpdk1"
                type: dpdk
root@juno:~/vm#

Does anyone know how to fix the error?


Thanks
