错误721 -- 在虚拟机中连接VPN, 显示验证用户名和密码之后出错

2011-05-20T01:11:00Z

解决方法:

为虚拟机选用桥接方式(Bridged Adapter) 连接网络, 而不是默认的 NAT.

最近在整理老的代码, 发现很久前做的小东西, 因为实在太简单, 没有继续保留源码的需要. 但也可能有非程序员需要, 故在此发布, 此后便可从硬盘删除.

Windows Live Writer 测试

刚安装了Windows Live Writer, 发点东西做测试.

代码(使用了VS的插件CopyAsHtml. 试过Writer的插件Paste from Visual Studio,但是背景色不能复制过来.):

64位虚拟机Guest OS安装错误：0xC0000225

1, CPU必须支持Intel VT-x/AMD-V。并且在BIOS及虚拟机软件中启用。

2, 虚拟机要启用 IO ACPI。
