如何找出Linux VPS的虚拟化类型？

有权访问VPS,我需要知道从终端运行哪种类型的虚拟化.

如何确定运行我的VM的虚拟化平台？ (OpenVZ,Xen,KVM等？)

解决方法

hostnamectl是你的朋友(需要systemd).

几个例子：

没有虚拟化的笔记本

$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

Xen的

$hostnamectl status
   Static hostname: pluto.gangs.net
         Icon name: computer-vm
           Chassis: vm
        Machine ID: beef39aebbf8ba220ed0438b54497609
           Boot ID: beefc71e97ed48dbb436a470fe1920e1
    Virtualization: xen
  Operating System: Ubuntu 16.04.2 LTS
            Kernel: Linux 3.13.0-37-generic
      Architecture: x86-64

OpenVZ的

$hostnamectl status
   Static hostname: mars.gangs.net
         Icon name: computer-container
           Chassis: container
        Machine ID: 55296cb0566a4aaca10b8e3a4b28beef
           Boot ID: 1bb259b0eb064d9eb8a22d112211beef
    Virtualization: openvz
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 2.6.32-042stab120.16
      Architecture: x86-64

KVM

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