判斷服務器是虛擬機還是物理機方式
一、如果是Linux：
1、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：
[root@centos7xj ~]# 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：
[root@centos7xj ~]# dmesg|grep -i virtual
Booting paravirtualized kernel on bare hardware
