查看CPU是否支援虛擬化

查看CPU是否支援虛擬化
一、Windows平台：
使用小工具securable。

使用者需要查看的也就是中的Hardware Virtualization選項。前面3種情況很簡單：
NO：CPU不支援
Yes：CPU支援，趕快去將BIOS裡的VT開關設為Enabled吧
Locked ON：CPU支援，且BIOS已經開啟該功能
Locked OFF：BIOS當前禁用了虛擬化技術，但是不確定CPU本身是否支援。遇上這種情況，先去找找BIOS裡面是否有Virtualization Technology並設定為Enabled，然後重新測試，若結果沒變，那也還是沒用。

二、Linux平台：
在終端執行cat /proc/cpuinfo命令，找到flags部分，如果其中輸出有VMX或SVM，即表明支援虛擬化技術。
cat /proc/cpuinfo | grep vmx ##(for Intel CPU)
or
cat /proc/cpuinfo | grep svm ##（for AMD CPU）
