第一种方式:dmesg命令
[root@test ~]# dmesg | grep -i hypervisor
[    0.000000] Hypervisor detected: VMware
[    0.001000] TSC freq read from hypervisor : 2903.999 MHz
[    6.311621] [drm] Max dedicated hypervisor surface memory is 0 kiB
第二种方式:lscpu命令
如果lscpu命令输出中出现Hypervisor vendor: KVM则表示是虚拟机,而出现Virtualization: VT-x则表示是实体机。
[root@test ~]# lscpu | grep Hypervisor
[root@test ~]# lscpu
