有没有一个命令或工具可以用来确定Ubuntu是否作为虚拟化程序（如VirtualBox或Qemu）的客户端运行，还是直接运行在物理机上？

virt-what
是一个可以用来检测程序是否在虚拟机中运行的Shell脚本。
该程序根据启发式算法打印出有关虚拟机的“事实”列表，每行打印一个事实。
如果没有打印任何内容，并且脚本以代码0退出（无错误），则可能意味着程序正在裸机上运行，或者程序正在运行在一种我们不知道或无法检测的虚拟机中。

This is printed for backwards compatibility with older virt-what
which could not distinguish between a Linux VServer container guest
and host.

kvm This guest is running on the KVM hypervisor using hardware
acceleration.
Note that if the hypervisor is using software acceleration you
should *not* see this, but should see the "qemu" fact instead.
Status: confirmed by RWMJ.
lkvm
This guest is running on the KVM hypervisor using hardware
acceleration, and the userspace component of the hypervisor is lkvm
(a.k.a kvmtool).

container.

Note that for KVM (hardware accelerated) guests you should *not* see
this.

node.

uml This is a User-Mode Linux (UML) guest.

virt
Some sort of virtualization appears to be present, but we are not
sure what it is. In some very rare corner cases where we know that
virtualization is hard to detect, we will try a timing attack to see
if certain machine instructions are running much more slowly than
they should be, which would indicate virtualization. In this case,
the generic fact "virt" is printed.
virtage
This is Hitachi Virtualization Manager (HVM) Virtage hardware
partitioning system.

运行`lspci`命令并检查字符串"VirtualBox"。
你可以运行`lspci | grep VirtualBox`命令。
你也可以运行`lsusb`命令，检查字符串"VirtualBox"。例如：`lsusb | grep VirtualBox`。
此外，`dmesg`命令也可用，运行`dmesg | grep VirtualBox`或`dmesg | grep virtual`。
你可以运行`lspci | grep VirtualBox`命令。

在运行虚拟机客户机的主机上可能会出现至少一条VirtualBox消息，所以我会取消dmesg选项。但是lspci和lsusb是可以使用的。 - Joe P
我认为命令行解决方案比安装软件包更好。如果您在系统上拥有超级用户权限（用于安装软件包），那么您是否可能不确定它是否是虚拟化的？ - Joe P
@JoeP 你说得对 - 除了... 如果你在所有机器上运行一个脚本，并且它需要知道主机是否虚拟化呢？ - Mei
