这个是ml2插件出问题，首先检测下是否安装，然后在检测配置。下面仅供参考，楼主找到对应版本的内容修改即可。

ml2_conf.ini

[ml2]

type_drivers = flat,gre

tenant_network_types = gre

mechanism_drivers = openvswitch

[ml2_type_flat]

[ml2_type_vlan]

[ml2_type_gre]

tunnel_id_ranges = 1:1000

[ml2_type_vxlan]

[securitygroup]

enable_security_group = True

enable_ipset = True

firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver



neutron.conf
