如何以编程方式知道我是否在VM中? [英] How can I programmatically know if I am in a VM?

问题描述

我希望能够从Windows和Linux上做到这一点.我知道可以通过获取sysinfo并使用与硬件标识符相关的经验法则来实现.

I want to be able to do so from both Windows and from Linux. I know that there are ways by getting sysinfo and using thumb rules related to hardware identifiers.

我想知道是否还有更基本的方法，例如查看内存地址/发出中断等.

I want to know if there is a more fundamental method, like looking at a memory address / issuing an interrupt etc.

顺便说一句，我正在尝试在Intel硬件上执行此操作，而我使用的虚拟化软件是Vmware Workstation和Windows HyperV.

BTW I am trying to do this on Intel hardware and the virtualization software I use are Vmware Workstation and Windows HyperV.

推荐答案

这是另一个有用的命令:

Here is one more useful command:

$ lscpu | grep -E 'Hypervisor vendor|Virtualization type'
Hypervisor vendor:     KVM
Virtualization type:   full

其他命令的示例输出:

$ sudo virt-what
kvm

$ dmesg | grep -i virtual
[    0.000000] Booting paravirtualized kernel on KVM
[    0.029160] CPU0: Intel QEMU Virtual CPU version 1.0 stepping 03

$ sudo dmidecode | egrep -i 'manufacturer|product|vendor|domU'
    Vendor: Bochs
    Manufacturer: Bochs
    Product Name: Bochs
    Manufacturer: Bochs
    Manufacturer: Bochs
    Manufacturer: Bochs
    Manufacturer: Bochs
    Manufacturer: Bochs
    Manufacturer: Bochs
    Manufacturer: Bochs
    Manufacturer: Bochs
    Manufacturer: Bochs
