一、Windows

在CMD里输入：

Systeminfo | findstr /i "System Model"

注意：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

二、Linux

1、dmidecode -s system-product-name

各类虚拟化返回情况

VMware Workstation

root@router:~# dmidecode -s system-product-name
VMware Virtual Platform

VirtualBox

root@router:~# dmidecode -s system-product-name
VirtualBox

Qemu with KVM

root@router:~# dmidecode -s system-product-name
KVM

Qemu (emulated)

root@router:~# dmidecode -s system-product-name
Bochs

Microsoft VirtualPC

root@router:~# dmidecode | egrep -i 'manufacturer|product'
Manufacturer: Microsoft Corporation
Product Name: Virtual Machine

Virtuozzo

root@router:~# dmidecode
/dev/mem: Permission denied

Xen

root@router:~# dmidecode | grep -i domU
Product Name: HVM domU

2、lshw  -class system

各类虚拟化返回情况

KVM

    capabilities: smbios-2.4 dmi-2.4 smp-1.4 smp

3、dmesg |grep -i virtual

各类虚拟化返回情况

VMWare

VMware vmxnet virtual NIC driver
 Vendor: VMware    Model: Virtual disk      Rev: 1.0 
hda: VMware Virtual IDE CDROM Drive, ATAPI CD/DVD-ROM drive

QEmu or KVM

If the "-cpu host" option has not been used, QEmu and KVM will identify themselves as:

CPU: AMD QEMU Virtual CPU version 0.9.1 stepping 03

otherwise, the host's CPU information will be used both in dmesg, or in /proc/cpuinfo. However, you should see something like:

[    0.000000] Booting paravirtualized kernel on KVM

In newer kernels that understand that they're running under paravirtualization.

Microsoft VirtualPC

hda: Virtual HD, ATA DISK drive
hdc: Virtual CD, ATAPI CD/DVD-ROM drive

Xen

$ sudo dmesg | grep -i xen
Xen virtual console successfully installed as tty1

Virtuozzo

# method #1
$ sudo dmesg
(returns no output)

# method #2
$ sudo cat /var/log/dmesg
(returns no output)

# method #3
$ sudo ls -al /proc/vz
veinfo  veinfo_redir  veredir  vestat  vzaquota  vzdata

注意：如果结果返回virtual，那么就是虚拟机，其他都是物理机。
