我正在尝试在单个 ubuntu 节点上设置一个简单的控制+计算。我正在使用开发堆栈。这是失败的命令：

neutron net-create --tenant-id 6fad6bf2ae9c49d3b19958abd59f3ce0 private-net

错误是：

NoNetworkAvailable: Unable to create the network. No tenant network is available for allocation.

这是我的相关配置 ml2 配置：

[ml2]
tenant_network_types = flat
extension_drivers = port_security
type_drivers = flat
mechanism_drivers = openvswitch
[ml2_type_flat]
flat_networks = public-physical-net,private-physical-net,dpdk-physical-net
[ml2_type_vlan]
network_vlan_ranges = private-physical-net
[ml2_type_gre]
tunnel_id_ranges = 1:1000
[ml2_type_vxlan]
vni_ranges = 1001:2000
[ml2_type_geneve]
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
[agent]
tunnel_types =
root_helper_daemon = sudo /usr/local/bin/neutron-rootwrap-daemon /etc/neutron/rootwrap.conf
root_helper = sudo /usr/local/bin/neutron-rootwrap /etc/neutron/rootwrap.conf
[ovs]
datapath_type = system
bridge_mappings = public:br-ex

这是ovs：

Bridge br-int
    fail_mode: secure
    Port br-int
        Interface br-int
            type: internal
    Port int-br-ex
        Interface int-br-ex
            type: patch
            options: {peer=phy-br-ex}
Bridge br-ex
    Port br-ex
        Interface br-ex
            type: internal
    Port "p255p1"
        Interface "p255p1"
    Port phy-br-ex
        Interface phy-br-ex
            type: patch
            options: {peer=int-br-ex}
