Windows：
在CMD里輸入：Systeminfo | findstr /i "System Model"
如果System Model：后面含有Virutal就是虛擬機，其他都是物理機
如果System Model返回信息內：后面含有Virutal就是虛擬機，其他都是物理機
物理機輸出：
C:\Users\Administrator>systeminfo |findstr /i "System Module"
System Boot Time: 8/20/2018, 06:30:23
System Manufacturer: LENOVO
System Model: 90DSCTO1WW
System Type: x64-based PC
System Directory: C:\Windows\system32
System Locale: zh-cn;Chinese (China)
或者用powershell命令：get-wmiobject win32_computersystem | fl model
Linux：
在bash里輸入：dmidecode -s system-product-name
或者lshw -class system
或者dmesg | grep -i virtual
如果結果返回包含virtual，則是虛擬機：
[youedata@localhost ~]$ dmesg |grep -i virtual
[ 0.000000] Booting paravirtualized kernel on Xen HVM
[ 1.034572] systemd[1]: Detected virtualization xen.
[ 1.065757] systemd[1]: Starting Setup Virtual Console...
[ 1.287144] xen_netfront: Initialising Xen virtual ethernet driver
如果返回如下，基於hardware，則說明是物理機：
[youedata@localhost ~]$ dmesg|grep -i virtual
Booting paravirtualized kernel on bare hardware
