nova list 查看虚拟机启动状态,正常是ACTIVE - Running
获取虚拟机的novnc访问链接,可以通过浏览器访问

nova get-vnc-console cirros-vol novnc

在浏览器中可以看到cirros已经在运行
用户名cirros 密码 cubswin:)

查看实例的subnet IP地址,正确获取

由于实验环境中的拓扑结构,192.168.100.0属于外网网段我们用处于此网段客户端来验证,在部署的环境中,内外网的相对的,并不是真实的公网

可以ping通,外网访问正常.这里要属于的是外网这个概念是相对.
我的192.168.100.0网段是无法上网的,但是在架构上来说是一个外网的网段
