如何找出 linux VPS 的虛擬化類型？

可以訪問 VPS，我需要知道它從終端執行的是哪種類型的虛擬化。

如何確定我的 VM 正在執行的虛擬化平台？（OpenVZ、Xen、KVM 等？）

hostnamectl是你的朋友（需要*systemd*）。

幾個例子：

沒有任何虛擬化的筆記型電腦

$ hostnamectl status
  Static hostname: earth.gangs.net
        Icon name: computer-laptop
          Chassis: laptop
       Machine ID: 18a0752e1ccbeef09da51ad17fab1f1b
          Boot ID: beefdc99969e4a4a8525ff842b383c62
 Operating System: Ubuntu 16.04.2 LTS
           Kernel: Linux 4.4.0-66-generic
     Architecture: x86-64

辛

$ hostnamectl status
  Static hostname: pluto.gangs.net
        Icon name: computer-vm
          Chassis: vm
       Machine ID: beef39aebbf8ba220ed0438b54497609

OpenVZ

$ hostnamectl status
  Static hostname: mars.gangs.net
        Icon name: computer-container
          Chassis: container
       Machine ID: 55296cb0566a4aaca10b8e3a4b28beef

虛擬機

$ hostnamectl status
  Static hostname: mercury.gangs.net
        Icon name: computer-vm
          Chassis: vm
       Machine ID: beeffefc50ae499881b024c25895ec86
          Boot ID: beef9c7662a240b3b3b04cef3d1518f0
