nova network-create 使用这个命令创建时提示error

RT：
命令：
nova network-create ne1t --bridge br100 --multi-host T --fixed-range-v4 192.168.0.0/24
ERROR:
ERROR (BadRequest): bridge_interface is required to create a network. (HTTP 400) (Request-ID: req-6f4ede34-4de3-4463-b8c4-e20cac119dc7)

但是我在nova.conf中间设置了：
network_api_class = nova.network.api.API
security_group_api = nova
firewall_driver = nova.virt.libvirt.firewall.IptablesFirewallDriver
network_manager = nova.network.manager.FlatDHCPManager
network_size = 254
allow_same_net_traffic = False
multi_host = True
send_arp_for_ha = True
share_dhcp_address = True
force_dhcp_release = True
flat_network_bridge = br100

请教这个问题是出在哪里，谢谢给位大神

检查下nova-network 是否正常运行
看下 nova-network 日志文件, /var/log/nova/nova-network.log

上面感觉缺少不少参数，这里仅供参考：

flat_interface=em1 
flat_network_bridge=br1 
network_size=256 
num_networks=1 

network_manager=nova.network.manager.FlatManager 
linuxnet_interface_driver=nova.network.linux_net.LinuxBridgeInterfaceDriver 
libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtBridgeDriver 
libvirt_vif_type=bridge 
multi_host=false 
send_arp_for_ha=false 
network_host=1.1.1.2
复制代码

注：上面设置的这些参数都是针对Flat及三种网络模式都会涉及到参数，我对参数进行下讲解:
flat_interface  ＃虚拟机网络之间通信接口地址，官方定义使用在flatdhcp模式下，也可以使用在flat
模式下，如果不定义此参数，需要在nova-manage network create时候指定--bridge参数

  flat_network_bridge #虚拟机网络通信接口桥接到的真实网卡名称，如果不定义此参数，需要在nova-manage network create时候指定--bridge_interface参数

network_size  #建立网段时可用地址数量，如果不定义此参数，需要在nova-manage network create时候指定--network_size=参数

num_networks  #建立网段时候默认的网络号，没太大意义，推荐使用nova-manage network create时候指定--num_networks参数

network_manager  #nova的网络模式

linuxnet_interface_driver  #接口驱动类型，可以设置为桥接和quantum libvirt_vif_driver  #libvirt使用的接口驱动类型 libvirt_vif_type  #libvirt的接口类型

multi_host  #在多计算节点情况下，如果开启此参数，相应计算节点将受控于本计算节点的nova-network服务去管理网络

network_host #在多计算节点并开启multi_host去指定网络主机(也就是nova-network)地址

gateway，flat_network_dns在这里没做讲解，还有network_size和num_networks推荐不使用，推荐在nova-manage network手工指定

建立实例网段
nova-manage network create --label=public --fixed_range_v4=1.1.1.195/30 --num_networks=1 --network_size=2 –gateway=1.1.1.1 --bridge=br1 --bridge_interface=em1 --multi_host='F'
