工具介绍：

使用帮助：

python openstack_manager.py --help

创建虚拟机：

python openstack_manager.py -c -f vmhost -t nslm

-c, 指定是要进行创建虚拟机 ， -f  指定要创建的虚拟机列表文件 ， -t 指定要给那个项目创建虚拟机

删除虚拟机：

python openstack_manager.py -d ip1 ip2

-d  指定要删除的ip ，可以跟多个

查看某个虚拟机信息

python openstack_manager.py -i ip1 ip2

-i 指定ip，后面可以跟上多个值

查看宿主机下的虚拟机信息

python openstack_manager.py -n node1 node2

-n 指定node，可以跟上多个值

更改虚拟机配置：

python openstack_manager.py -u ip -F flavor

-u指定某个ip， -F 指定某个配置

批量ping：

python openstack_manager.py -p -f vmhost

-p指定进行批量ping，-f指定文件

从文件中获取创建虚拟机的命令

（创建过程中某个虚拟机出错，可以进行查看创建虚拟机命令进行手动创建)

python openstack_manager.py -g -f vmhost -t

-g指定要进行获取命令，-f指定文件，-t指定项目

-f 指定文件的文件格式：

批量ping是检查ip虚拟机是否存在，指定的文件也是参照此格式

一行一个虚拟机

其它使用信息：

脚本中的flavor对应的flavor id，项目帐号密码和镜像ID，数据库帐号等替换成自己生产环境中的信息
