Linux CPUInfo如何檢測虛擬化支持

在Linux系統中，可以通過查看/proc/cpuinfo文件來檢測CPU是否支持虛擬化。以下是具體步驟：

方法一：使用grep命令

1. 打開終端。

2. 輸入以下命令并按回車鍵：

   grep -E 'vmx|svm' /proc/cpuinfo
   

   • vmx 是Intel的虛擬化技術標識。
   • svm 是AMD的虛擬化技術標識。

3. 如果命令輸出中包含vmx或svm，則表示CPU支持虛擬化。

方法二：使用lscpu命令

1. 打開終端。

2. 輸入以下命令并按回車鍵：

   lscpu | grep -E 'vmx|svm'
   

   • 同樣，vmx 表示Intel的虛擬化技術，svm 表示AMD的虛擬化技術。

3. 如果命令輸出中包含vmx或svm，則表示CPU支持虛擬化。

方法三：手動檢查CPU特性

1. 打開終端。
2. 輸入以下命令并按回車鍵：

   cat /proc/cpuinfo | less
   

3. 在輸出中搜索flags字段，查找是否包含vmx（Intel）或svm（AMD）。

示例輸出

如果CPU支持虛擬化，你可能會看到類似以下的輸出：
