求助：swift stat时，Account HEAD failed或Auth GET failed

我的是KVM的虚拟机，2G内存。
操作系统是CentOS6.5 x86_64的，用的是Icehouse版本。

[root@control ~]# swift stat
Account HEAD failed: http://controller:8080/v1/AUTH_6298a6f29bcf43489a051975b36df694 401 Unauthorized
[root@control ~]# swift -A http://192.168.25.7:5000/v2.0 -U service:swift -K waftest stat
Auth GET failed: http://192.168.25.7:5000/v2.0 200 OK
