VM can't ping each other in DPDK scenario with nic x710

Setup:
contrail 5.0 + DPDK + openstack
NIC: X710
DPDK_UIO_DRIVER: igb_uio

VM can obtain the ip address, but can't ping each other.

After debugging, found that vhost0 can't be seen from vrouter agent container. It can be seen outside the container.

It seems it failed to add vif0 from the log of vrouter dpdk agent.
