Expanding the contrail-openstack cluster

[menkeyi]

[root@ctfdeploy contrail-ansible-deployer]# ansible-playbook -i inventory/ -e orchestrator=openstack -e ansible_sudo_pass=abc@123 playbooks/install_openstack.yml
TASK [memcached : Copying over config.json files for services] *************************************************
failed: [10.49.252.201] (item=memcached) => {"changed": false, "item": "memcached", "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'ipv4'"}

The problem appears on the ens160 network card and the vhost0 network card

[root@opcontroller ~]# ip a
2: ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 00:0c:29:39:e8:7f brd ff:ff:ff:ff:ff:ff
inet6 fe80::20c:29ff:fe39:e87f/64 scope link

。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
9: vhost0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN group default qlen 1000
link/ether 00:0c:29:39:e8:7f brd ff:ff:ff:ff:ff:ff
inet 10.49.252.201/24 brd 10.49.252.255 scope global vhost0
valid_lft forever preferred_lft forever
inet6 fe80::20c:29ff:fe39:e87f/64 scope link
valid_lft forever preferred_lft forever

Before deployment, the IP is on the ens160 network card. After the installation is complete, contrail configures the IP on the vhost0 network card. Why can't I find the IPv4 address on the ens160 network card when expanding the cluster? How can I expand it?
