忘记oneadmin的默认密码
opennebula默认的密码是在/var/lib/one/.one/one_auth中。
opennebula使用sha1来加密用户密码，所以我们使用sha1加密器加密123456并得到加密字符串，然后登录进数据库，在opennebula数据库中的user_pool表中记录了用户的信息，而且body字段中 间的数据即为对应用户的密码加密字符串。
我们用得到的加密字符串来替换user_pool表中用户名为oneadmin列的body字段中 间的数据。
然后修改/var/lib/one/.one/one_auth文件内容：oneadmin:123456
好了，这下就能用密码123456登陆了
