openstack【juno】入门 【实例篇】二十六：创建实例(neutron)

大神  我Openstack创建的虚拟机不能Ping通  那段配置文件也加上了  

虚拟机网络配置是这个样子的  

有可能是哪有问题呢
错误日志也没找到

谢谢大神了

创建实例的时候出现
root@controller:/home/jxy# source admin-openrc.sh
root@controller:/home/jxy# nova get-vnc-console demo-instance1 novnc
ERROR (CommandError): No server with a name or ID of 'demo-instance1' exists.
这个问题是怎么回事啊？

实例创建完之后的状态是error，而且可以获取到网络
root@controller:/home/jxy# nova list
+--------------------------------------+----------------+--------+------------+-------------+---------------------+

镜像问题？

恩,原来用的是这个cirros-0.3.3-x86_64镜像,后来换成ubuntu14.04,现在可以创建实例
但是在实例中安装系统的时候出现了这个问题,这是怎么回事啊?

我在创建实例的时候失败，显示如下错误要怎么弄呢？

原因比较多的，参考这个试试

【已解决】启动云主机时，No valid host was found.

根据你提供的日志看不出是那的问题。楼主看看其他日志信息

大神，我ping网关不通，我在实例里ifconfig了一下，发觉eth0根本没获取到IP，为什么会这样？
