在VM Manager中搜索VM Server时出现这个错误。
按照VM Server以及VM Manager后，通过指定IP地址，让VM Manager自动寻找VM Server，结果JOB运行报错，详细的错误信息为：

由于关键性信息确实，所以无法判断导致错误的原因。即使是在metalink或GOOGLE中查询，也得不到任何有价值的信息。
虽然在VM Manager中得不到有意义的信息，但是在VM Server上，却可以得到更详细的信息，通过检查var/log/ovs-agent.log文件，获取到下面的信息：
[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)!
这次信息就明确多了，显然是由于VM Manager中配置的密码不正确所致，在VM Server上修改oracle用户密码：
[root@server2 ~]# ovs-agent-passwd oracle
Password:
Again:
在搜索VM Server时使用这里修改的密码，VM Manager成功的发现了VM Server信息。
