virtualbox 打不開ubuntu解決

裝了一個win7x64，準備打開ubuntu12.04，後來居然報錯（最新版的virtualbox，VirtualBox-4.3.18-96516-Win）：

也沒找到什麼緣由，網上查了以後，禁用了win7自帶主題，發現也沒有奏效。

貼一下log，也沒看出因此然：

後來安裝了舊版本：VirtualBox-4.2.16-86992-Win

雖然能打開了，安裝tools的時候居然不識別xwindow。

好吧，因而下載其餘版本試試看，下載了一個4.3.10 版本的virtualbox，終於能夠用了。

這件事情給個人經驗教訓是對於有些軟件，不要嘗試最新版本。百度貼吧上對於virtualbox有各類亂七八糟的問題的討論。

這個東西畢竟是免費的，也不能怪他。以前用的vmware也用的很不順心，後來只能用virtualbox。感受vmware的bug比virtualbox多多了。
