How does linux determine whether it is a virtual machine?
This article mainly explains "how linux judges whether it is a virtual machine", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let Xiaobian take you to learn "How to judge whether Linux is a virtual machine"!
Methods: 1. Judge by dmidecode command, which can obtain information about hardware, with the syntax of "dmidecode -s system-product-name";2. Judge by lscpu command, which can display detailed information of CPU, with the syntax of "lscpu option."
Operating environment: Linux 7.3 system, Dell G3 computer.
How Linux determines whether it is a virtual machine
1、 dmidecode -s system-product-name
The dmidecode command lets you get information about hardware on Linux. The function of dmidecode is to decode the information in DMI database and display it in readable text form. Because DMI information can be manually modified, the information in it may not be accurate information for the system. dmidecode follows SMBIOS/DMI standard, and its output information includes BIOS, system, motherboard, processor, memory, cache, etc.
2、lscpu
The lscpu command displays CPU details, such as CPU manufacturer, architecture, CPU number, model, clock frequency, and cache information.
At this point, I believe that everyone has a deeper understanding of "how linux judges whether it is a virtual machine". Let's actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
