一例Vmware Server版本不一致导致的问题
在新的电脑上安装完Vmware Server2.0.2后，导入以前的虚拟机文件。在左边的虚拟机列表中选中虚拟机后，右边的窗口空白一片， 无法查看虚拟机的配置信息也无法启动虚拟机。
在系统日志看，看到如下内容：
然后到目录：C:\Documents and Settings\All Users\Application Data\VMware\VMware Server下查看虚拟机的日志信息。依次查看hostd-0.log到hostd-9.log日志文件的内容。
发现如下比较重要的信息：

在网上寻找了很久，这篇博文解决VMWare Server 2.0 出现 Cannot Connect to VMX的问题的方法也不奏效。而且，vmware社区http://communities.vmware.com/index.jspa的很多帖子也没有给出有效的方法。这个Cannot connect to VMX问题也是个比较棘手的问题。
解决方法：原来我犯了一个低级的错误。曾经下载了vmware server 1.0.6 和 vmware server 2.0.2这2个版本的安装程序。因为以前的虚拟机环境不存在了，在新的电脑上安装的时候，就选择了vmware server 2.0.2。出现了上面的问题，曾经还重装了两次。 最后看了一篇自己曾经写过的文档《在VMServer1.0.6中配置SQL Server 2005故障转移群集》，才意识到自己选错vmware的版本了。多么低级的一个错误啊，白白折腾了一天多的时间。
曾经还出现过如下的无法登录的问题：The server was unable to process your log in request.Please check with your server administrator.
解决方法：设置使得登录用户对虚拟机文件所在的目录拥有权限。
