算节点上只能ping通该实例内部IP，ping不通浮动IP

试过将控制节点及计算节点路由转发都打开了，没有效果。
root@hwnode1:/home/ubuntu# sysctl -p
net.ipv4.ip_forward = 1

root@hwnode2:/home/ubuntu# sysctl -p
net.ipv4.ip_forward = 1收起

#net.ipv4.ip_forward=1
去掉注释
sysctl -p收起

不是手动建的
在计算节点上创建虚拟机实例时自动生成的。应该是nova.conf配置文件里面指定了br100才会自动生成br100吧。收起

是不是查看/etc/sysctl.conf

看看控制节点的路由转发是否打开了收起

计算节点上没有nova-network服务,那个br100是你手动创建的吗?收起

还有,看看你控制节点的路由条目收起

你这个架构好奇怪呀,呵呵

你设置一下安全组看看,允许计算节点IP的ICMP通过.收起
