这http://www.ubuntu.com/download/cloud/install-ubuntu-openstack指南要求 3 个逻辑私有网络 IP 地址范围：
Dynamic range — that has as many IPs as there are total NICs connected to the network
Static range — that has as many IPs as there are machines connected to the network
Floating IP range — that has as many IPs as instances that you'll have in your cloud
我不清楚我是否需要全部三个范围还是只需要其中一个。
