在 Control node修改nova.conf

去掉这个后缀

配置为空

重启nova-api服务

[root@open-controller-1 ~]# systemctl restart openstack-nova-api.service

[root@open-controller-1 ~]#

　　

后面创建的实例查看主机名不带后缀了

[root@open-controller-1 ~]# sh show_vm.sh

open-compute-1.inner.hzdgjy.cn           instance-00000018              demo10                         provider=10.0.8.118
