区分物理机与虚拟机

如何使用命令区分物理机与虚拟机？

• 虚拟机

[root@test ~]# dmidecode -s system-product-name
VMware Virtual Platform

[root@test ~]# systemd-detect-virt
vmware

[root@test ~]# hostnamectl status
Chassis: vm
Virtualization: vmware

[root@test ~]# cat /proc/scsi/scsi
  Vendor: VMware   Model: Virtual disk     Rev: 1.0

[root@test ~]# lspci
00:07.7 System peripheral: VMware Virtual Machine Communication Interface (rev 10)

[root@test ~]# lscpu |grep vendor
Hypervisor vendor:     Xen

• 物理机

[root@localhost ~]# dmidecode -s system-product-name

[root@localhost ~]# systemd-detect-virt
none

[root@localhost ~]# hostnamectl status|grep -A2 Chassis
