檢查系統是否裝在VM虛擬機上

檢查某台機器是否裝在VM (Virtual Machine)虛擬機上，用lscpu指令：

• lscpu | grep -i 'hypervisor vendor'

如果有結果跑出來，那就是在VM上：例如說

• Hypervisor vendor: KVM，裝在KVM virtualization
• Hypervisor vendor: Xen，裝在Oracle VM

關於Hypervisors提供者還有例如：

• KVM (Kernel Virtual Machine)
• RHEV (Red Hat Enterprise Virtualization)
• Xen / Citrix XenServer
• vSphere / VMware ESXi
