1、判断虚拟机两种方式 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

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
