先添加主機：
然后出現(xiàn)提示：
在網(wǎng)上找了一圈，基本上沒什么回復，沒辦法，還得自己搞。 查看日志進入/var/log/cloud/managerment，看管理服務器的日志：
tail -f management-server.log
查看日志發(fā)現(xiàn)出現(xiàn)異常信息：

查看VT是否打開因為沒打開VT，所以導致不能添加Host的異常，打開VT后，再次添加，添加成功！ cloudstack當修改mysql的bind_address時導致連接不成功修改參數(shù)后導致tomcat不能啟動，查看日志，得到如下信息：

允許任意IP訪問；
如果指定ip，那么不知道為什么本機就不能訪問，會導致一些異常，所以我修改為任意IP都可以訪問，再重新授權。
grant all privileges on *.* to root@"%" identified by "password" with grant option; flush privileges;
