Hi
First, thanks for the reply. vHost-user(s) can bind to the related socket right
now, but I have another problem. I followed the link
(https://software.intel.com/en-us/articles/using-open-vswitch-with-dpdk-for-inter-vm-nfv-applications)
and while booting a VM with Fedora-Cloud-Base-23-20151030.x86_64.qcow2 image
by qemu, it gives me the following error, even so I can login the VM but and I
cannot connect the VM via ssh or cannot connect to the Internet from the VM.
Therefore I cannot transfer anything into the VM. By the way, I don't know it
is related to the OvS DPDK or not?
Thanks in advance..

Maybe the code you are using does not have the below commit? Try
removing the file manually before re-running.

netdev-dpdk: Clean-up after vHost User port delete
Unregister and delete the socket associated with a vhost-user
port when the port is deleted and/or the switch is brought down.
Do not delete the socket if the vhost-user device is still attached
to the guest.
