4、删除网络ID，并检查

neutron agent-delete ID
neutron agent-list

systemctl stop libvirtd.service openstack-nova-compute.service
systemctl stop neutron-linuxbridge-agent

6、清除数据库记录

# nova库
use nova;

# 查询nova主机
select host from services;
select hypervisor_hostname from compute_nodes;

# 删除主机
delete from nova.services where host="要删除的主机名称";
delete from nova.compute_nodes where hypervisor_hostname="要删除的主机名称";

7、查看结果

nova service-list
neutron agent-list
