工具介紹：
創建虛擬機會使用多線程隊列的方式去控制同時創建的虛擬機數量
如果在創建的虛擬機比較多，會2次創建。第一次會在各個宿主機上創建一臺，其余的會再第一次創建成功后創建。
因為第一次創建需要傳輸鏡像會比較慢，在宿主機上已經有對應的鏡像后，再次創建相同鏡像的虛擬機，不再需要傳輸相應的鏡像（所有相同鏡像的虛擬機共用同一個后端鏡像，openstack對鏡像管理使用copy on write技術）
查詢和更改主要都是通過查詢數據庫實現。
其它功能自測。 |
使用幫助：
python openstack_manager.py --help
創建虛擬機：
python openstack_manager.py -c -f vmhost -t nslm-c, 指定是要進行創建虛擬機 ， -f 指定要創建的虛擬機列表文件 ， -t 指定要給那個項目創建虛擬機
刪除虛擬機：
python openstack_manager.py -d ip1 ip2-d 指定要刪除的ip ，可以跟多個
查看某個虛擬機信息
python openstack_manager.py -i ip1 ip2-i 指定ip，后面可以跟上多個值
查看宿主機下的虛擬機信息
python openstack_manager.py -n node1 node2-n 指定node，可以跟上多個值
更改虛擬機配置：
python openstack_manager.py -u ip -F flavor-u指定某個ip， -F 指定某個配置
批量ping：
python openstack_manager.py -p -f vmhost-p指定進行批量ping，-f指定文件
從文件中獲取創建虛擬機的命令
（創建過程中某個虛擬機出錯，可以進行查看創建虛擬機命令進行手動創建)
python openstack_manager.py -g -f vmhost -t-g指定要進行獲取命令，-f指定文件，-t指定項目
-f 指定文件的文件格式：
批量ping是檢查ip虛擬機是否存在，指定的文件也是參照此格式
| nodename instance_ip flavor |
一行一個虛擬機
其它使用信息：
腳本中的flavor對應的flavor id，項目帳號密碼和鏡像ID，數據庫帳號等替換成自己生產環境中的信息
