建立虛擬機器會使用多執行緒佇列的方式去控制同時建立的虛擬機器數量 如果在建立的虛擬機器比較多，會2次建立。第一次會在各個宿主機上建立一臺，其餘的會再第一次建立成功後建立。 因為第一次建立需要傳輸映象會比較慢，在宿主機上已經有對應的映象後，再次建立相同映象的虛擬機器，不再需要傳輸相應的映象（所有相同映象的虛擬機器共用同一個後端映象，openstack對映象管理使用copy on write技術） 查詢和更改主要都是通過查詢資料庫實現。 其它功能自測。 |
使用幫助：
python openstack_manager.py --help
建立虛擬機器：
python openstack_manager.py -c -f vmhost -t nslm -c, 指定是要進行建立虛擬機器 ， -f 指定要建立的虛擬機器列表檔案 ， -t 指定要給那個專案建立虛擬機器
刪除虛擬機器：
python openstack_manager.py -d ip1 ip2 -d 指定要刪除的ip ，可以跟多個
檢視某個虛擬機器資訊
python openstack_manager.py -i ip1 ip2 -i 指定ip，後面可以跟上多個值
檢視宿主機下的虛擬機器資訊
python openstack_manager.py -n node1 node2 -n 指定node，可以跟上多個值
更改虛擬機器配置：
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指定檔案
從檔案中獲取建立虛擬機器的命令
（建立過程中某個虛擬機器出錯，可以進行檢視建立虛擬機器命令進行手動建立)
python openstack_manager.py -g -f vmhost -t -g指定要進行獲取命令，-f指定檔案，-t指定專案
-f 指定檔案的檔案格式：
批量ping是檢查ip虛擬機器是否存在，指定的檔案也是參照此格式
| nodename instance_ip flavor |
一行一個虛擬機器
其它使用資訊：
指令碼中的flavor對應的flavor id，專案帳號密碼和映象ID，資料庫帳號等替換成自己生產環境中的資訊
