查看配置文件：

/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]

 

#

# From neutron.ml2

#

 

# List of network type driver entrypoints to be loaded from the

# neutron.ml2.type_drivers namespace. (list value)

#type_drivers = local,flat,vlan,gre,vxlan,geneve

type_drivers = flat,local

 

# Ordered list of network_types to allocate as tenant networks. The default

# value 'local' is useful for single-box testing but provides no connectivity

# between hosts. (list value)

#tenant_network_types = local

tenant_network_types = vlan

 

driver支持flat和local两种，但是tenant_network_type却使用vlan类型导致：

No type driver for tenant network_type: vlan. Service terminated!

 

解决方法：

type_drivers = flat,vlan,local

 

结果：

[root@localhost ml2]# systemctl restart neutron-server

[root@localhost ml2]# systemctl status neutron-server
