linux查看是实体机还是虚拟机

1、判断虚拟机三种方式

1、dmesg|grep -i hypervisor

[root@localhost ~]# dmesg|grep -i hypervisor

[    0.000000] Hypervisor detected: VMware

2、lscpu 查看Hypervisor vendor:超管理器厂商

[root@k8s-master ~]# lscpu

Architecture:          x86_64

CPU op-mode(s):        32-bit, 64-bit

Byte Order:            Little Endian

CPU(s):                8

On-line CPU(s) list:   0-7

Thread(s) per core:    1

Core(s) per socket:    2

Socket(s):             4

NUMA node(s):          1

Vendor ID:             GenuineIntel

CPU family:            6

Model:                 79

Model name:            Intel(R) Xeon(R) CPU E5-4610 v4 @ 1.80GHz

Stepping:              1

CPU MHz:               1795.841

BogoMIPS:              3591.68

Hypervisor vendor:     VMware  #虚拟机

Virtualization type:   full

L1d cache:             32K

L1i cache:             32K

L2 cache:              256K

L3 cache:              25600K

NUMA node0 CPU(s):     0-7

Hypervisor vendor: KVM #虚拟机

Virtualization: VT-x #实体机

KVM：

　　虚拟化技术有两种类型的实现：

　　Type-I : hypervisor------>VM

　　Type-II：host------>VM----->VMS

3、systemd-detect-virt

#虚拟机

[root@localhost ~]# systemd-detect-virt

vmware

#实体机

[root@master242 ~]# systemd-detect-virt

none
