在VM Manager中搜索VM Server時出現這個錯誤。
按照VM Server以及VM Manager后，通過指定IP地址，讓VM Manager自動尋找VM Server，結果JOB運行報錯，詳細的錯誤信息為：

由于關鍵性信息確實，所以無法判斷導致錯誤的原因。即使是在metalink或GOOGLE中查詢，也得不到任何有價值的信息。
雖然在VM Manager中得不到有意義的信息，但是在VM Server上，卻可以得到更詳細的信息，通過檢查var/log/ovs-agent.log文件，獲取到下面的信息：
[2011-04-16 13:21:46 25970] ERROR (OVSAgentServer:108) Unauthorized access attempt from ('10.0.10.173', 59424)!
Traceback (most recent call last):
File "/opt/ovs-agent-3.0/OVSAgentServer.py", line 103, in do_POST
auth(username, password)
File "/opt/ovs-agent-3.0/OVSAgentServer.py", line 42, in auth
raise Exception('Authorization failed: user does not exist or password error.')
Exception: Authorization failed: user does not exist or password error.
[2011-04-16 13:21:46 25970] INFO (OVSAgentServer:169) code 403, message Unauthorized access attempt from ('10.0.10.173', 59424)!
這次信息就明確多了，顯然是由于VM Manager中配置的密碼不正確所致，在VM Server上修改oracle用戶密碼：
[root@server2 ~]# ovs-agent-passwd oracle
Password:
Again:
在搜索VM Server時使用這里修改的密碼，VM Manager成功的發現了VM Server信息。
