I was using VirtualBox in Fedora and Vista but it happened to use all CPU resources in guest machine and the VM seems very slow. You can observed this problem by opening the task manager and see the CPU utilization at 100%, and core cpu usage is around 90%.

I searched about this problem but found only the questions and no useful answer. I even tried the VirtualBox 3.0 beta1 which supports SMP in VM but ended up facing blue screen of Vista guest. Seems there is no solution.

I just remebered VirtualBox said its software virtualization is better than Intel VT-x, should I try to disable VT technology? I uncheck the default setting of VT and reinstalled the guest system. All things goes smoothly!

But unfortunately VirtualBox seems slow to me and I will try KVM instead.

最近工信部老在玩笑话，很好玩，花了劳动人名4000多万搞出个怪胎，出了个“驴爸”。驴爸那真是一头蠢驴，虽然我没有用过，但我也清楚的知道但凡这种垃圾软件是活不长的。听说驴爸还偷了别人的东西还硬要说是从自己肚子里面长出来的，丢了自己的驴脸还把全国人民的脸都拉长了。

好吧，玩不动“驴爸”生了个怪胎那也扛不住了，转移视线又来玩“股沟”了。

这下“股沟”好玩了，搜索功能被关不说还被要求禁止境外搜索，最可怜的是被人搞了还要交钱。或许交的钱有用来填“驴爸”的怪胎钱吧。关键是专家叔叔还教会了我一个单词boobs，根据dict.cn提供的资料，这个单词词义如下：

**n. 笨蛋,蠢材

n. (俚)女性的乳房** 专家叔叔还说搜索这个词可以看到好多不该看的东西呢……来，试试哟。果然如此。
更搞笑的是，“百毒”也非等闲之辈：

来，在看看“股沟”的“儿子”如何呢？

哟，虽然google.cn已经挥刀自宫了，但是google.fr(法国)还是可以找到。而且很简单，只需要把.cn改为.fr就ok了。
没搞懂怎么切换到google.fr？高级搜索里面找答案吧。
工信部下一个焦点是哪儿呢？搞“百毒”？抑或把对外电缆拆了，整堵墙在那儿放着名曰“绿坝”？来个物理隔绝？不得而知。

我想我可能落伍了哟，老早之前就注册了Facebook，但一看界面就像“校内网”——说实在“校内”也还真垃圾——一下子就没有了兴趣。算了，还是规规矩矩的玩博客吧。

根据长时间的观察，现在的博客已经走向了低谷了，很久没有看到有谁有个留言了。大家都在玩社交网站，交了一大堆朋友，一会儿一个留言，一会儿一个评价。QQ也学得好，整啥子抢车位、挖白菜——整个就一浪费时间。我看我博客的站点统计，流量基本上还是来自于我的hesicong.net域名的流量。大部分都是以前写的技术类文章。现在也懒了，也不想写了。最近用微软的东西越用越冒火，GDI+性能太次，串口类有一个BUG……

整个博客的衰落到现在的境地，让我联想起一些现象。以前QQ刚流行的时候，大家都加这个加那个，都想成为好友，见面时不时聊一聊。看看现在呢，好友上面的数量至少上百了吧，上线的寥寥无几，基本上都是隐身的。QQ除了用来追追女娃，看看照片，整个就一浪费CPU、内存的东西。好吧，你说不用吧，又总是心痒痒想打开，又总是想到可能有朋友要联系。但一上来才发现是个可有可无的东西。好吧，有时候无聊就上会儿手机QQ，一看没人聊，算了，关了，玩N-GAGE。

我猜想社交网站估计也差不多这样，国内学了很多，校内、开心、QQ空间、饭否，还有一些我还不甚了解。每天用着就想看看有没有朋友留言，没有留言还要制造机会叫人家留言。没事看看菜是不是被哪个偷了，车位是不是被占了。每个人其实都很闲，但一问：老大最近如何？答案多半都是：很忙。真不知道忙到哪儿去了。

我也一样哟。每天挂着QQ，随时看看QQ空间，再看看MAIL，再看看Wordpress。其实看看MAIL就好了，Wordpress都没有必要打开，就知道有没有留言了。

以前的博客，就像是私家别墅，时不时有贵宾过来看看；现在的社交网站，就像赶集买东西一样，很火。但我真不知道这东西能够火多久。

最后看来，我还真是落伍了，那就落伍吧……

This is the third day after the No.9 bus tragedy in Chengdu, my hometown. When I went to Meten by bus, I noticed a phenomenon that many people looked around to find the hummer or tried to find out where is the emergency switch of the door. And more people prefered to stand beside the door or near the window.

Today, government announced the investigation of the fire that someone might bring some gaslione to the bus. According to the video of the whole burnning process, I could concluded that the bus must be fired by people because the fire started from the inner part of bus. Government also made out a plan to modify the window of the bus which has an air conditioner and would take more investment to buy new buses.

We must learn something from this terrible thing. First is not to take any dangerous things to the public area. Second is to be careful of people near you if he brings some suspicious things. Third is when someone is in terrible trouble, you must take your full ability to help them get out of that situation. Fourth is learn some safety knowledge in case you’re in trouble.

But, in the end, hope everyone is safe and happy everyday!

早上老爸发条短信说9路公交车烧了起来，死了很多人，我当时还以为是什么小道消息或者恐怖袭击呢，结果一看新闻果然是啊，那么强的火，那么脆弱的生命……

晚上坐512公交车回来，整个车就是个拖拉机一般的响声，还开着空调，听发动机声音是柴油机。还好，晚上7点过出发的车人少的可怜，找个靠窗户的位置坐下了，听着听着英语睡了一觉。

现在坐飞机要落到海里面，坐火车要撞散架，走路都要遭70码，在家吧，地震……

好吧，安安心心的，平平安安的，小心翼翼的，祝愿大家都幸福安康~
