virbr0 8000.000000000000 yes默认情况下，会生成网络private，生成命令在stack.sh文件中：
# Create a small network
$NOVA_BIN_DIR/nova-manage --config-file $NM_CONF network create "$PRIVATE_NETWORK_NAME" $FIXED_RANGE 1 $FIXED_NETWORK_SIZE $NETWORK_CREATE_ARGS可以让生成的instance使用此默认网络，而不用新生成网络vmnet。
生成linux网桥相当于一个网卡，设置IP后外部能访问此网桥。
5 设置vm的IP
登录http://9.186.50.180/，通过控制台进入vm，设置IP。
这篇关于nova-network创建实例之FlatManager的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
