Question

如何查看linux系统是物理机还是虚拟机

Answer 1

Windows：
在CMD里输入：Systeminfo | findstr /i "System Model"
如果System Model：后面含有Virutal就是虚拟机，其他都是物理机
或者用powershell命令：get-wmiobject win32_computersystem | fl model
Linux：
在bash里输入：dmidecode -s system-product-name
或者lshw -class system
或者dmesg | grep -i virtual

虚拟机（下边有VMWar）：
[root@test ~]# cat /proc/scsi/scsi

物理机：
